In all likelihood, this mic probably no longer has all or most of the original, sound shaping elements present in a genuine Neumann U47: tube, transformer, and maybe capsule as well.

My advice;
Buy this mic only after you have auditioned its sound thoroughly, and after understanding that this microphone will not have the sound or a genuine U47.

By the way: I find the ad copy a bit misleading, frankly.

This is not a comment on the sound of this mic- it may be stunning, for all I know-  but a comment on how unfortunate it is that vendors are so sloppy (or deliberate?) with placing their product in the vicinity of one of the most sought-after microphones in the world.

I agree with Klaus.  Having owned one of these, I can say they are fine mics, but I prefer a U47 which has not been "Blue'd."  Their value should be substantially less than an unaltered U47.  But they are well put together, and if you are comfortable paying that type of money, then have have it.  

Just understand that it is not longer a real U47.  That being said, I still made some epic recordings with the one I had.

If you live near a Guitar Center, you might want to ask them what they want for a Blue "47", as they bought a large lot of them and I've been told by one of their pro audio reps that they have been having trouble selling them. There may be a deal to be had if you like the mic.

Before BLUE went ""consumer""/GC   they offered several small runs of custom microphones  some RFT  7151 rebuilds -  many reworked Lomo mics etc.  Cleaned up RCA ribbons, M49s  Even some perfect Original vintage Neumann examples. (I bought a mint SM2 from them that is still killer 15 years later)  I have a very interesting MM5 I bought from them as well as some KU3as etc.  (also parts etc.)

I have owned many mics from this "pre BLUE" BLUE period.  Many of them have some vintage components   some do not!

From my exclusive 1st hand expirience Sometimes:

 THE MICS WERE MISREPRESENTED WHEN SOLD I WAS TOLD THE 47S  HAD ALL ORIG STOCK OLD PARTS WITH NEW WIRING AND COSMETICS  --THIS IS NOT THE CASE.  

ALSO EVERYTHING  THAT  I BOUGHT   FROM  THEM  WAS SAID TO COME WITH A  WITH A "VERBAL" ""LIFETIME"" """WARRANTY"""  THAT IS NOT BACKED UP IN MY EXPIRIENCE.  When I called BLUE  with a problem after the GC-ifacation  I was told by BLUE that "We are no longer dealing with or supporting those mics"

Many of the things they sold me outperformed other seemingly healthly vintage mics in my collection. The U47s certainly being an exception.

If you see a "47" with an ef86... It is Possibly a "new" Blue mic with a value of well less than %50 of a real one.(IMO)  It Also comes with a completly different sound. not terrible and not a 47.

I have found that a mic with many if not all new variants of pieces is not a "refurb".

 The word refurb is sometimes used to perpetuate an illusion.  I think the idea is to confuse the buyer that it is a vintage item to get a vintage premium price.  BLUE certainly interacted with me in this regard.(IMO)

Having said that again, some of the work that the Old BLUE did was nice,  some of the only things I kept from them was a pair of reworked Leipzig 7151.  I have no idea what they put in the bayonett mounts they are not m7s,   They sound great though
(keep in mind this was years before they went big) Whatever they did to a LOMO 1913a pair  sounded amazing..  

**These 47s are the worst of it if you ask me.

For the record I have not listened to any of their new products and am not commenting on them.

Unless it is priced right(?) or you love the sound of it (I liked my Vintage Real and Clone U47s Much better...)  BEWARE

Something very cheesy about a different design in the same chasis when it is represented as the real thing and It Is Not.

BTW, I bought my Blue 47 direct from them, and it was not misrepresented as to being all original.  That was the point of putting the EF86 badge on it.  But I did not know enough at the time to know that the VF14 and BV8 were so integral.  

Was that GC that misrepresented it, John?  Or are you saying Blue did?

I was told it was an orig refurb with orig old style parts from BLUE,  when I asked about it  and why it said "ef86"  more of the story came out.  I sold them for a 1k loss each.
to GC  funny enough.

I allready had previous expirience/owned some vintage neumans so I was able to see "hey this is not that.."

I was a bit naive I guess. I was fairly young and new  so I think they may have let it fly a little further.

With such a mic, it seems that at some point, the only "U47" parts that would be left are the logo badge and the serial number badge. I understand that many of these have Blue capsules, and with a new transformer, different tube (and, as I understand it, entirely different electronics to work with that tube), as well as possibly a new housing tube and basket... exactly what makes it a "U47"?

If I buy a Blue Cactus, pry off the badge, and put a genuine U47 serial number badge on it, is it a U47?

Klaus,

the mic in the listing claims "serial #5557". Am I correct in thinking that would have been among the last U47s produced? In that case, it would have been Nuvistor-equipped, K47, and which transformer?

I asked Skipper about the capsules, and he said that most of them were K47 backplates, reskinned with their tension ring that said "Blue" on it.  Very nice sounding, though.  I compared it against a K47 that had been reskinned by Doug Walker, and I actually thought the Blue one sounded better!  It had more low end.

I am not at my data base right now. but serial numbers of 5000+ was the end of the run, as fare as I recall.
As to "originally Nuvistor equipped" U47s- to my knowledge, Neumann never sold a U47 mic with the Nuvistor ex factory but offered Nuvistor kits to U47 customers when they could no longer supply VF14 as spare parts.

I recently acquired Telefunken, Model U47, Blue Modified s/n 0203B.

I am trying to find out any information about this Mic. Is any of it the original components. Is it true U47 sound?

Anyway to find out anything about it?

Thanks.index.php/fa/13929/0/

Unfortunately, it is likely 100% clone.  No original parts.

Some of the early Blue 47s were actual refurbs with new parts added as needed, but at a certain point Blue began producing knock-offs.  Sound is similar to a real U47 with K47 capsule, but not quite as good as the original.   However, they can still be very good tube mics.

You can find out a lot about what components are used in this mic by posting several close-up pictures of the mic-amp and capsule area insides here; then wait for expert opinions to give you the lowdown.

I don't remember what forum it's on, but I've done extensive evaluation of this question before, perhaps more than once. Give a search to that "other" pro audio forum.
