Title: Telefunken-USA 'VF14k' Tubes or: How Authentic Must It Be?
Post by: brett on October 20, 2008, 04:19:41 PM
Has anyone heard a vintage U47 with a new TELE VF14 in it?

From Ebay auction-


U47 Short Body Restoration


If you are looking to purchase a vintage U47 that is completely original, this is not the mic for you. However, if you are interested in a vintage U47 that has been restored to original spec and sounds absolutely amazing, like it did out of the box 50 years ago, then this mic IS for you.

This mic was one of two short bodies that were permanent fixtures at a church in Tennessee. They were sent to Telefunken USA for restoration approx one year ago. Upon their arrival, the body tubes were dented and damaged from screw holes drilled in them for mounting purposes. The mics were in rough shape due to the lack of care and maintanence. The original GN8B output transformer was failing and the VF14 tube was shot. Upon further inspection, we determined that the capsule was in fine shape and sounded great. We decided that some serious work needed to happen to this microphone, including special attention to the output transformer and the vacuum tube.

This U47 started its life as a U48, this is why it includes the grey matte finish plating on the headgrill instead of the nickle plating found on the U47s. The capsule is the original issued K47 capsule. We have included the Frequency Analysis plot of this capsule with the attached photos.

Here is a detailed part by part breakdown of the parts and components included in this microphone system:

- Original brass ring K47 capsule
- Original silver matte finish headgrill and internal capsule mount and components.
- Original GN8B rewound to standard BV8 using original metal material by AMI/ TAB Funkenwerk
- Original oil filled Bosche output capacitors
- Original circuit boards and metal "decking" and chasis rails inside microphone
- Original Neumann tube socket

- New Telefunken USA power supply and 25' Gotham Audio GAC7 cable with Binder USA and Tuchel style connectors. This PSU and Cable system will mate and interface with original U47s set up for VF14 tubes.

- New VF14k tube replacement for the VF14 tube. This is a newly manufactured solution for bad VF14 tube. A direct plug and play physical and sonic replacement for the VF14, the VF14k operates at the same voltages, with no modification to the original circuit or power supply. If so desired, a real VF14 can be placed into the circuit of this mic at any time, without worries or needs to modification.

- New polarizing capacitor at the top of the mic
- New resistors on the circuit board near the transformer
- New wooden microphone box (short body)
- New Shock Mount

This microphone will include a 1 YEAR WARRANTY on all parts and labor, no questions asked. If the capsule, tube, psu or transformer fail within one year of purchase, they will be replaced at no charge. Vintage Tones reserves the right to end auctions early as Items are being sold locally. Zero feedback and negative feedback buyers must contact us before bidding. Buyer pays shipping charges.

Well, it's being sold by Vintage Tones / Tele USA, so it would make sense that they put the VF14K in it.  I'm still really curious to hear what they sound like.  The xray I have of one of them looks correct.

A correction though about their description: The Bosch caps are not oil filled.  I'm trying to figure out if that's the original capsule bias resistor and and grid shunt resistor.  It's hard to see.  They are smaller than what I am used to seeing in U47s.  It's not the type T-USA uses, so it's very likely.  I don't have any U48 or short body U47 innard pics to compare it to.

The capsule in that mic does not seem to be a stock Neumann K47.
(The diaphragm ring mounting screws do not look original.)

Everyone wants to sell adulterated or vintage-like wares and put them in as close proximity to the original, legendary mics as they can be put with words- from naming replacement parts using the same or almost same names as the original, to asserting original-like performance.

If these kind of mics sound great, they should sell themselves even at steep prices, like this one, and they should not need any further (in my opinion) contentious assertions.


We urgently need replacement tubes for U47/48 with the performance of a genuine VF14. I have well-working original factory spec VF14M specimens to compare these new tubes to, and am ready to test. So, let's hear the Telefunken-USA copy of the original Telefunken-made VF14- I am genuinely curious.

Where are these VF14k tubes? Are they being made available for objective and subjective testing by any others than those who buy the whole mic system? And if not, why?
I will pay for shipping both ways and I promise to keep the results of testing confidential, if requested by the sender of one of these tubes.

Sorry to resurrect a thread over 15 months old but someone in another thread on another forum made a link to this and it is the first I had seen it.

The tubes are ONLY sold with the systems [and sometimes for 'restoration repair'] as they're A) a time consuming bitch to make and B) we can only produce enough per month to cover our requirements for current production with an extra or two for 'restoration repair' [in a good month].

That said, if you would like to evaluate one the next time we have one we can spare for a month or so I'd be happy to send it to you for evaluation.  I know I have your address somewhere but as I'm inherently rather lazy if you could email it to me cnf@t-funk.com the next time we have one we can spare, we will send it to you for evaluation.

Fair enough?

And to clarify, the X-Ray JJ had posted WAS NOT of a Vf14k. It was bullshit. I actually bought one because I believed that T-USA had actually pulled it off because of these pictures. As well as been promised a spare that was never delivered.

Great sounding mic though Smile

FWIW, I checked around the office... nobody there has any knowledge of you being sent an X-ray of anything.  No "chicanery" or "hoodwink" attempt was generated by anyone I can find at TELEFUNKEN Elektroakustik nor with any "known associate" I can find.

Fletcher, thanks for looking into that.  For the record, I wasn't implying that anybody in there was responsible.  Sorry if I gave that impression.  I don't even know that I was seriously thinking that, even though of course the notion crossed my mind.  I was simply saying that somebody took advantage of my trust, and pulled the wool over my eyes, and I passed on bad info.  Furthermore, I have no way of finding out who that was, any longer.  But whoever did it, by definition, is responsible for chicanery, and I feel the fool for passing along bad info.

This is a good example of the questionable reliability of internet information, and how we all can learn from a mishap like this one:

Actually, it was YOU who first posted the x-ray without corroborating or confirming what it showed before you hit the send button.  
So, despite your probably noble, innocent intentions, ultimately it was your decision to spread the questionable picture over the internet and attach to it Telefunken-USA's name. No need to invoke third parties who let you down.

That is one of the reasons why I am such a hardass about any third-party information on this forum.
Title: Re: Telefunken-USA 'VF14k' tubes starting to surface

Well I definitely didn't think T-USA would be fool enough to do something like that (although I didn't think they would try to call a glass tube "electronically and sonically identical" to a real Vf14 either. I thought Grosser's pics had to be fake when I had seen them.)

But having said that, they certainly did NOTHING to stop the notion from spreading on two very popular forums. Even before the hoopla I emailed T-USA (since I was privy to these pics months before they showed up on PSW) and they refused to respond in writing. Telephone conversation only. Same with the VF14k spare I was promised. After finding out about the glass tube encased I was nervous about the life expectancy and requested a back up tube. I was told supply is short due to high demand but that they will be caught up within a year.

Again verbal only, and as you can probably guess - no spare ever sent.

I do like the product though, and I absolutely think T-USA should be upfront and proud of their product - glass tube and all! This I told them directly. Hopefully you, Fletcher, will be part of a better culture between company and customer that the product deserves.

Yeah.  My bad.  Sorry about unwittingly spreading misinformation.

As far as Tony's point, there's a difference between clever marketing, and outright deception.  I can point to two occasions in particular where the company in question here was in involved in outright deception, including this tube situation.  Hopefully Fletcher's presence there will discourage any future episodes like this, and we can simply judge them on whether or not we like the microphones.

This thread is bound to become interesting, the VF14 is quite a hot topic if you ask me.

Anyhow.
The VF14 if my U47 died on me the other day and the mic needed service anyway so I sent it to Peter Drefahl of www.drefahlaudio.com here in Germany.
He fitted a VF14 fet substitute from Andreas Grosser.

The M7 cap was also reskinned while he was at it so I cannot really compare, but the thing sounds gorgeous.

Andreas Grosser's VF14 fet subsitute seems to be available in Europe ONLY. This seems illogical to me. Maybe legal issues with TFK USA.
Or are TFK USA the sole US distributor of  Grosser's VF14 fet substitute?

What do I know - speculations, speculations...

Keep 'em coming.

Post by: Klaus Heyne on January 28, 2010, 02:27:22 PM
Sound aside, why did you not replace the VF14 with another one?

I am sure you are aware of the fact that the collectible value of the U47 is affected in direct proportion to the parts that would need to be acquired to make the mic all-original again.

With other words: this mic is now worth the exact amount less on the open market that it would cost to buy a well-working VF14. (Can someone with good English language skills make this last sentence more elegant?)
Plus, you spent more money for the VF14 solid state work-around.

Why am I so adamant that this is a bad idea? Because such extreme customization is rarely appreciated by potential buyers of a classic like the U47: the pool of potential buyers who would be interested in a mic with an extreme alteration shrinks so much that the price inevitably drops substantially.

And because, despite frequent assurances by owners to "never sell this mic because I love it so much", this as every other classic mic will of course be offered for sale, sooner or later, sometimes against the best intentions of the owner (illness, financial trouble, new interests, death...)

Typically, substitutions of core parts on a classic mic make more sense when the mic was already butchered to begin with. I.e. the collectible value was already suppressed from the get go.

If I owned a U47 with a broken VF14, I would probably do the same. These microphones are tools and were made to make recordings. In fact it is sad, these U47's are collectables.

One reason to have a substitute tube could also be to make the microphone useable until you run into a good opportunity to buy the original tube.

From my understanding Andreas Grosser makes a VF14 enclosure with FET electronics inside it that simulates the original VF14.
So it is a drop in replacement without any other mods.

If that is the case, and no modifications, not even of the cable, power supply or supply voltages are involved, the reduction in value of such a modified mic will be limited to the cost to obtain a well-working VF14.

And further, if that is indeed the case, I think it is a pretty good (at least temporary) solution. If you do not have a replacement VF14 to hand, and you want to spend a bit of time searching for the best candidate for you, the fet at least gives you a working mic with a great capsule and xfrmr.

 Honestly I'd love to find a well working VF14m to get everything back original.
But as everyone knows this requires money, time, maybe luck if you go the eBay route.
It may not happen at all.

(...) Also, I tend to power up the mic way more often than I used to when the thing still ran on VF14. I just didn't feel comfortable to use it for scratch tracks


I'd like to offer you and every other concerned parent of a U47 my perspective of acquiring a VF14 on the open market in the year 2010:

A studio owner recently asked me to look at an eBay auction for a VF14 (non-M) in Germany.

Seller: 100% positive feedback.
Identity of the seller: revealed in the auction description, including address and phone number.
Warranty on the tube: yes, money back until 1 week after receipt.
Communication: seller immediately e-mailed the studio owner who agreed to send me the tube for testing, if he won the auction.

When the tube got to me, a week after it was sold to the studio owner for his high bid of about $1K (!), I plugged it in, and noticed right away that it had a comparably  high (+6dB) noise floor. I notified the studio owner who immediately contacted the seller who immediately offered to take the tube back, but also agreed that I could continue the test a little bit longer. Result: the tube which probably had not been used for a while, or was previously used in an underheated circuit, regenerated itself fully, to a noise floor after a week of burn-in barely 1dB worse than the best VF14M.

Studio owner happy, seller happy, everyone happy.

P.S.: Never worry about powering up a VF14 tube too many times: the ramp-up speed is so gentle in U47/NG1 applications that I cannot think of a gentler way to start up any tube.

There is no question that a fully working VF14 is the better option than any replacements out there, either non mod or mod needed.

But, were do we get all those replacement VF14 from?

27000 made approx. 3500 U47 made, of the 27k made only 1/3 microphone grade, etc. etc.

So a VF14 for over $1K? That is in my world money wasted, last time I had a customer with a gone bad VF14 and I sourced him a
good working VF14 for warrantied price of $1500 he asked me if I am crazy.

Hello Klaus,

the question is, is a 47 worth $10K or more?

They might be collectors items by now and the price is driven up artificial. We are now at $1K lets wait 5, 10, 20 years, do you really think that someone will pay $10k for a tube that belongs into $100ooo mic?

My only point is $1000 for a tube that can die any moment or life for 6 month, 2 years or maybe 10 years....


Best regards,
Title: Re: Telefunken-USA 'VF14k' tubes starting to surface
Post by: Klaus Heyne on February 02, 2010, 09:18:27 PM
Oliver, I feel differently about both of your arguments:

1. Yes, if a U47 will ever hit $100,000, I think, spending 1/10 of the mic's value will be a reasonable price for a VF14.

There are plenty of examples from other areas of collectibles, like from the guitar world, where the price of an essential component will usually rise commensurate with the price of the item itself: if you want to find a zebra PAF humbucker for a $100,000.- Les Paul Standard guitar from 1959, you will pay now several thousand dollars for it. That PAF used to be $100.- when I worked at Don Wehr's Music City in SF in 1975, and the going rate for a '59 Les Paul was around $2,000.-

2. Of course, any tube can bust at any moment. But, as long as a thorough evaluation of the VF14 preceded its purchase, its chance for long-term survival in a U47 is better than any other microphone-specific tube I know of.

Your overarching question of "is it worth it?" is daily answered by those who pay the current market prices for vintage mics, as they did in the past, when the prices were much lower.

Who or what determines the value of a tool? The user who agrees to the price, in negotiation with the seller. That, then and now, is the true value of the item, not what we wish it to be (so that more of us could afford it, so that these fine tools don't end up unused in bank vaults, etc.)

Prices for vintage mics are not artificially 'driven up' as far as I can see: nobody is forced to pay more than he thinks the item is worth, not even by those 'collectors' who will never use the microphone in a studio. Even they will not pay more than what the microphone will yield in the open market.

The relationship between low supply and high demand and the resulting (steadily higher) price of valuable recording tools does not even change when the equivalent sonic value or emotional attraction is offered in a currently-made microphone (the KHE is one mic that proves my point.)

That wouldn't surprise me, and it'll be a similar situation to the tone-attorneys who spend silly money on vintage guitars.

I don't think exceptionally good mics can make the difference between a piece of recorded music being good or great. Plenty of exceptionally good records have been made with "average" studio equipment.

Regarding maintaining investment value, yeah, if the market still demands the mic, then fit a VF14 there if you are concerned about resale value. That makes sense.

There will always be those who don't appreciate the context for pricing, especially in this time of disposable products, immediately available, for disposable prices.

Beautifully articulated response, Klaus. And of course, I'm just as frustrated as the next guy with the high prices.

As to the value of things, like tubes, here's a little education about collectibility:

1959 fender telecaster pots and original capacitor - $695.00

http://cgi.ebay.com/1959-fender-telecaster-pots-and-original -capacitor_W0QQitemZ390150976837QQcmdZViewItemQQptZGuitar_Ac cessories?hash=item5ad6cf7545#ht_500wt_956

This is an example of the high end of market.  This stuff routinely goes for stupid amounts of money.

A bakelite switch tip for a '50s Les Paul?  $400, usually.  

A U47 without a VF14 is not a U47.  It's that simple.  A '58 Les Paul with Lindy Fralin pickups might be very nice, but it's no longer a real '58 Les Paul.  

When I had my Blue 47, people used it and never complained that it didn't sound like a 47.  They loved the sound of it.  But it was not a 47.  

The mentality of vintage gear is the same now as it is for vintage instruments or antiques.  They serve a function beyond their collectibility, but people want to get their money's worth, and expect to get at least their initial investment back, when they sell it.  

A Flying V with a Floyd Rose loses its value.  A Bijar carpet that has been shortened to fit the home of the previous owner loses its value.  A 47 with an EF14, or any other non original part, essential to the sound, is less valuable.  And people will pay to get that VF14, the same that they will pay for that Les Paul switch tip.  

We might think it's folly, but it's reality.

Hello Klaus,

I agree with all your points if I were an investment counselor. I do understand your points about why the price is O.K. but have to question it at the same time.

Let me put it in a different perspective: if the price of replacement parts or even entire items rise a certain level, the honesty will get blurred by the value of the item.

You quoting the vintage guitar/instrument market very often as a reference, but I never saw a place where the basic idea of the emperors new clothes applies more.
It is not a question anymore if an equal product could be produced, the simple answer is, that it can not be done.
This answer is blurred and distorted by the insane prices those items comment.

Lets talk about tools. I agree with you that there is not a direct replacement for a VF14. There are several drop-in replacements that might come close or are even there (matter of opinion), but even if a 100% reissue would enter the market, the honesty would take  backseat (already has) and it would be never the same, because otherwise the so-called "original" would lose money!

In the end, no studio owner or engineer would care about a mod if there is a tube that would sound like a VF14.
Given the fact that the U47 is crossing over from a good recording tool to a collectors item, the basic honesty will be overlooked. That is the basic rule in investment!

It will be very interesting to see what happens within the next ten or 20 years with the current microphone crop.

Best regards,

There are very few example of new microphones (or guitars) that would make me want to swap one out for a vintage example- I have not heard any small diaphragm mics that would make me want to lose my nickel KM mics.

There are new mics, as pointed out in the 'Lucas' thread which people seem to love. The KHE's  value has sky-rocketed (I have yet to hear one), and my experience with the new Bock 5 zero 7 has to be the most exciting new mic I never knew that I would hear- that mic is a steal.

All of these "finally to come" new mics that hang with the giants still have me no nearer to selling my vintage examples. I feel the old classics have their place only more secured by the new offerings. Some of the best new mics of today hang in there with some of the classics, but do not render them less useful.

If there would be a major upset in technology, like the development from crystal mics (telephone mics) to tube condensers, that might do to the classics what digital photograpghy did to film..  but we'll see.

Make some music with these mics for now !
Best Sounds,

I would MUCH rather have a pair of Wunder CM7GTs, AND a pair of KM54s than a single vintage U47 at the same price.

If I had a U47 I would sell it instantly. When you buy those kinds of things you are not just buying mics, you are buying something else entirely. Even Klaus has posted here that he would not own a U47 because it was worth the same as a car. (Don't recall that post. K.H.)

I love vintage gear, and I still go for gear that is selling for way less than the new version. My electric guitar of choice is the 1950s Gibson ES-225, which usually sells for less than a new one, sometimes 50% less.

I think Oliver, Wunder and Bock have proven that if you can still make mics that equal the vintage ones; certainly the U47 has been recreated at an acceptable level, but the KM5x series has no known peers- but then the vintage samples of those are still relatively inexpensive (about the same as a new KM140).

Wunder demoed their CM7 FET last week and it was pretty convincing to me that I would be silly to buy the vintage FET at 2x the price of the new Wunder.

Stephen,

This will probably sound offensive and I don't mean it that way at all -- and it is not directed at you in particular.

I think it's silly for one person to tell another what's silly when it comes to living one's life, spending one's money etc.  You get one shot at life and if you want to spend a ton of money on something (and you have/can spend the money without endangering someone) then you should.  There may be better bargains, others might not do what you're doing, but O.K., do it if you want to.  That's the only way to live life -- follow your heart (but lead with your head).

So when are we going to see some decent KM54 clones? Has anyone made any serious attempts? Peluso has the P-28. Any other more serious C28 attempts? KM64/66?

I'm really glad you posted that, as I've been wanting to ask for a while. It seems a KM54 clone would be a pretty hot selling and useful tool if someone could get it right.

Speaking as the owner of a '58 Les Paul, and a few U47s, as well as owning a couple of Lucas mics, a couple of Bock mics, and having used the Wunder CM7, there is no way I would sell my '58 Les Paul or U47s.  In fact, that would probably be my last guitar I would ever sell, and one of my U47s will be in the last three mics I sell, with my M49s and 251.  

New guitars and mics do a similar thing, or an entirely new one, that might get you in the ballpark.  I have a new Gibson that I've put a lot of work and love into, to improve it and make it as close to an old Gibson as possible.  But when you have a good example of the older mics or instruments, I'd have to say that new stuff only gets me about 80% of the way there, and that last 20% is the part that makes the hair on my neck stand up.  

Every time somebody brings their new Les Pauls into the studio, the '58 beats it.  I've put my U47 up against almost every one of the 47-type mics available, and nothing was preferable or equal.  

Would I rather have 2 CM7GTs and a pair of KM54s than a U47?  No way.

'Clone' implies pretty strict adherence to the building blocks that made the originals famous: super-thin nickel diaphragms, AC701, or equivalent (no, wait, there is no equivalent, as the tubes were commissioned and  custom-made by Telefunken for Neumann, with some help from Schoeps), decent custom-wound transformer, super-compact, discreet-component electronic configuration, etc.

Even if such technical hurdles could be overcome, I don't believe the numbers are there. Such a mic would cost several thousand dollars; that lofty territory runs out of air supply pretty quickly.


P.S.: It would be really swell if we could all agree on a common usage definition of 'clones' and 'copies' and 'recreations' and 'remakes'. It's not that we don't have fairly precise distinctions within the English language between these terms, but we often seem to casually (and sometimes deliberately?) misapply these terms.

If we go by definition, a clone or a copy is an exact duplicate.
Recreation or remake seems to allow for some variance from the original.

I thought that word would stick in someone's craw, and I'll buy that.

My point was to include worthier types of attempts similar to what has been done with the U47 with companies such as Wunder, Flea, etc...

I know that in the strictest sense there may be only one modern mic that tries to be a literal copy of the original U47, but there are a handful that try to recreate the effect within "reasonable" boundaries using modern and/or more available parts.

I am excluding the bottom feeders in any case. There are a good few nice mics that aspire to "recreate" the most famous LDCs of yore, but I'm not aware of any serious "recreations" of the great SDCs. Seems like a gaping hole.

@piedpiper,  The Orig KM nickel mics are affordable enough and able to be maintained  they rarely go wrong,  in addition "re-issue" mics usually do not measure up to their historical counter parts

@ jj, There might be some problem with your '58 LP if there is hair on the neck, Especially if that hair is standing up!

@Stephen, I think JJ has it nailed plus I have heard those Wunder Mics in several comparisons  every single orig good working U47 bested it fairly severally -not to say that I would not be content to use the fine Wunder mic on a record though My and other U47s leave me with JJ's conclusion I would not trade a couple pairs of Wunders for One killer U47 ...  Lead Vocals!

I understand these comparisons are hard to come by and close can be remakable but I also agree with the "feeling"  of that it gets you about 80% of the way there in cases of U47

just my opinion though    best wishes

Barry: certainly everyone has a point where the price of a certain item becomes silly -- for them.

For me, the U47s, 58 LPs, and Pre-War Martins have hit that point. This is not to say that I think anyone would be silly for buying or owning one, as people have very different budgets, needs, and business models. I can see JJ's case where having the very best gear in the studio can both attract big-budget clients and get the best sound, and very well may be worth the price tag.

For me, a pro musician with a home studio, I have to stretch the dollar to the max., and for me it makes good sense to go with some of today's top gear that is modeled after the vintage originals.

Thanks John and Klaus for the perspective on tube SDCs, and sorry to derail.

Also, I agree that there may be no real replacement for the exact (and yummy) flavor of a real U47. I do think there is at least one better (and more affordable) modern version than the Wunder, which has on several occasions has come across as a bit hard and bright in comparison to the originals. I preferred the BeezNees T-1 by far on one occasion.

(...) We have all heard about the platinum track recorded through a SHURE SM57.

The funny thing is in regards to business model I would venture out and say JJ gets No more business because of his wicked collection (of mics) but I bet he likes having and using that stuff! It is the same with my place  I bet if I had worse mics it may help the business. Like U87's and other easily recognizable things.

Back on topic, Klaus- Did Fletcher send you the tube as discussed?  I know if it were others hinting about that conversation you just may hold their feet to the fire -  So ??

I have a '64 jazz bass that I wouldn't sell or trade for anything or any amount of money. It's the best instrument I've ever heard. It won't make a bad song a good one, and nobody hires the bass,  they hire me. It's still a tool, they're all tools, and their value as artworks has little to do with their quality as tools. You can't get too hung up on this stuff, although I enjoy vintage gear as much as anyone. Whatever helps you do great work is a great tool for you.

From my understanding Andreas Grosser makes a VF14 enclosure with FET electronics inside it that simulates the original VF14.
So it is a drop in replacement without any other mods.

API


Soon I am buying a repairable U47 which Gunter Wagner will be repairing, and he suggested the best sounding option is the Andreas Grosser drop in replacement.

Since the U47 I am buying had a Nuvistor in it, and is not working, I'm going to try Gunter's suggestion. At least the owner had the sense to keep the tube sockets and other stuff after the Nuvistor modification, so I won't be spending on those parts.

As I have an all original U47, I will be able to make a good comparison. If I have the time, I'll post a couple of sound bytes on my website of the same instrument recorded at exactly the same time and distance, with both mics.

Expect the soundbytes to be on my website in about two months or so, while the mic gets rebuilt.

Cheers

I will do so. Thanks for the suggestion. This will uncover the sound of the Grosser replacement solid state replacement.

I edited my post, it was long, boring, and I saved it on my laptop for future reference. I thought it was starting to go to off topic...

I am interested in listening to the Telefunken USA VF14k tube replacement... once I have two U47s', maybe I can persuade Fletcher to send me one tube for testing purposes. I can afford to buy it, if need be. And I'll have two different U47s to test the same tube with.

Go ahead and start getting jealous, it's not a sin (that I know of...)
