tascam da-30 mk II service manual
« on: July 20, 2007, 01:13:43 pm »

hello-

does anyone have the service manual for a tascam da-30 mkii?  i'm trying to sell mine, but it's giving me the error 01 (transport issue) code and i'd like to try and fix if possible, but not looking to sink much/any cash into it, as even working - they only fetch $150 or so.  but still it seems a shame to just toss.  i have the regular user manual which is useless as far as technical info goes.

the bit of research i've done (mostly from eddie ciletti's site) makes it seem like it's something to do with the ALPS transport.

thanks,
nk

Error code 01:

Yes I have the manual, but it's easier to tell you what to do:

open the tray, power down the unit, remove the top cover, remove the transport (4 screws and a few conectors... I think there's a long 'transport load spring' also...) then turn the transport over.

Looking at the bottom of the transport, there's a small, -no, make that tiny- black rubber drive belt which goed from a very small pulley to a rather larger pulley directly next to it...

That's the one. Buy more than one replacement (they're only a buck or two) and put a new one on. -then take the spare, and place it in a baggie and tape the baggie up inside the lid of the DA-30MkII... Put some sort of friendly note in there for the next time the new owner of the machine needs to replace the belt.

Oh... and send me a couple the belts will ya... -I NEVER seem to be able to have any around when I need them in a hurry! Wink

-Seriously, if you need part numbers etc. I can check when I get home (it's where my service manual is) and I'll go in on an order with you if you're ordering from them... -It'll save putting two orders in, after all.

Oh... I should add:

You're not looking for a BROKEN belt... what happens if these machines sit unused for a period is that the belt gets "used" to being in one position, and takes on that sort of "egg-shape". Then it gets a little bit loose.When eventually you try and load a tape, the small pulley spins, but the belt doesn't want to
'grab', and the larger pulley doesn't turn as it should... hence it throuws a loading error.

I'll look 'em up when I get home tonight, and maybe scan the exploded diagram to show where they go...

Presumably when it's trying to load, you're hearing a motor spinning faster than usual? or mabe slipping and "surging" in speed... -right?

i'll check again tonight, but here are the notes i made last nite:

what i'm seeing now is i power up, put in tape. press close, tape goes inside, then drops down while silver head rotates - protective shelf opens on DAT tape, tape spools out onto head and what look to the be tape lifters push the tape out away from the cassette - head rotates a while while machine tries to do something, but fails. the tension on the tape is nothing like a regular tape machine, in fact it appears to be slack almost.

it's been so long since i've used it i have no idea what usual or unusual would be.  but as the head rotates and it "tries to do something" i could see that maybe as slipping or surging.

well i'll be.

i took it apart and saw the small little gears and drive belt you're talking about and touched it with my finger, which was apparantly enough to unstick it.  everything seems to be working a.o.k. now.

i even got to hear something i recorded/played like 5 yrs ago. wow.  completely forgot doing that.

don't kill yourself scanning if you haven't already!!

thanks much,

Okay, I won't scan the page, but I do have the part number for you; (see later).

Pop the belt off... you'll see that it doesn't sit "circular"... It's Egg-shaped. It needs replacement because it will slip one time while you're trying to UNload a valuable DAT, and the tape will chew because it didn't get wound back into the shell before it was ejected...

Trust me... -it's like being able to SEE the future before it happens! Wink

The TASCAM part number is V00013500A [Belt, LDG].

I'd ALWAYS replace as soon as you get your first Error 01: Basically what you did when you 'nudged' it was to move the 'curved' part of the belt onto the smaller pulley. It's now a lottery as to when the two flat parts chance to end up either side, so that the belt is once again in the same orientation that it sat in for a long time... at that point, if there's a tape inside the machine, you're looking at a strong possibility of a shredded tape on eject... Since it's such a cheap fix, it's madness to play 'Russian Roulette' with valuable old tapes (with no backups, I'll bet!) so I usually replace them on sight... To the point where I have two machines here that I need new belts for, and no belts left... and I bought ten belts last time!!!

So enjoy the machine AT YOUR PERIL... if you're ejecting a tape, PLEASE wind to a spot on the tape where there's LOTS of silence... I used to ALWAYS leave the first minute of a DAT blank and ALWAYS rewind completely before ejecting. People who eject in the middle of a song without first rewinding have only themselves to blame when the machine ruins the only copy that they have by chewing a tape on eject.

My motto was: "If it happens once to you, you have a chance to learn; -if it happens twice, you haven't learned anything!"

Hi Keith,

I'm very glad to have stumbled on this post.

I have two Tascam DA30 mk2 DAT machines. Both have had Error 01 before and I've sent them back to Tascam which was rather expensive. I'm also thinking of selling one of them now, but it has just thrown the Error 01 at me after a long period in storage.

Where is the best place to order the belts? Direct from Tascam UK, or is there a better third party supplier?

Thanks very much.

Phil,

If you can find a place which sells rubber belts, then contact them and ask how they measure them to determine dimension (eg: circular diameter, folded linear length etc) then see if they have some belts which match the ones on your DA-30MkII. Don't forget that they're also square-section, and you may also possibly need to measure the section size.

Failing that, if you just remove the belt from one of them, then allow it to sit on your bench for a week or so, you may find that it returns from "egg-shaped" to circular. (not a permanent solution, but one which allows you to see the problem and confirm that replacing the belt once it's regained a circular 'memory')

Hope that helps. -Tascam USED to have a service place in Buckinghamshire, I think, in case you're near there.

Keith,

Thanks very much for getting back to me so quickly.

Panic Music near Cambridge seem to be the UK Tascam repair agents now. I've had dealings with them before and they are good, though whether they are prepared to supply belts for D.I.Y. repairs is another matter.

Teac UK Ltd. apparently, according to Google, still have a head office in Watford. I'll start my enquiries there and let you know how things develop.

Phil - CPC (www.cpc.co.uk) are usually a good place for generic drive belts. The only problem is that they have a 40 pound minimum order if you want to avoid their small order charge (which was 5 pounds when I last did a small order).

Cheers

I wanted to thank you for this post.  It has helped me immensely.  I purchased a used Tascam DA-30 MkII with very few hours of use on it.  But I immediately got error 01 when loading a tape.  I followed your instructions about replacing the belt and it was very easy to do and fixed the problem.

By the way, I ordered the loading belt directly from Tascam (on 2/27/09).

You can reach them at 323-727-4840
The part number as listed on their invoice is: V00013500B
it is also listed as BELT, LDG DA-30MK2/DA-P1

I hope this helps anyone else dealing with this issue.

Ah. Looks like they've revised the part number because the suffix has changed from an 'A' to a 'B'.

Presumably this is because this part failing with the tedious predictability of an unloved season!

Happy to help. -at one time I had about fifty of these things to look after. -I still own a couple.

I also found this thread interesting.

Seeing as I have a Tascam DA-40 DAT machine, does anyone know how similar the 30 and 40 models are?  I'm wondering if I should look into getting a few of these belts at some point.

Thanks a million for this post. I just purchased a used but mint-looking condition DA-30 that I could not try on site because it was just brought in from the cold and I wouldn't turn it on without letting it heat up... Unfortunately I got really sad seeing that it won't recognise my tapes and throw an Error-01 message....
I saw this thread, got the cover off and the loading unit out, removed the small belt and gave it some hairdryer treatment to regain its normal shape... remounted the whole and it works like a charm...
At least I know what's causing the error and I'm going to order 1-2 belts right away.

Thanks again!!!

I have found a much cheaper replacement belt from MCM electronics. Part # 42-1770 is less than a dollar and so far works great in my DA-40. The DA-40 and DA-30 have most of the same transport mechanisms. This belt is also known as Pioneer part PEB1072. Do NOT use the PRB SCY1.5 it is too thin.

Thank you for the great info on this thread!  

Many of us have wondered over the years of the Error 1 problem.  Just a quick note to USA owners of a quick fix while waiting for the proper belt from Teac/Tascam.  You can use an "O" ring as well from Lowes (plumbing department).  BrassCraft, part number 0535.  Anyone else: Any "O" ring with the dimensions of: 10mm I.D (13mm O.D) x 1mm OR 1.5mm Wall.  Hope this helps for the quick fix while waiting for parts.

This thread encouraged me to pull my old DA-30 out of hiding.  I recall error messages upon loading last I used it (10 years ago...?)  

Do any of these belt or O-ring remedies apply to the plain old DA-30?  I disassembled mine and saw a drive belt, and three small loading belts but didn't notice anyting as small as 10mm....

?

The DA-30 (MkI... though it was never marked 'MkI'... the one with three silver knobs, two of them friction-geared) used a very different transport... and it didn't use the same loading belt arrangement.

Check for head rotation (instead of being seized, which I've seen) as well as rotary encoder working correctly...

I checked the drum and indeed there was stiction..!  When I rotate the drum by hand there is a slight 'papery' noise.. hmm.  I'll need to locate my archive of DATs to verify the error codes... (where did  I put those?)

Hi all,

Went to use my DA-30mk2  this weekend for the first time in months.  The tape loaded in and played once.  The second tape loaded in and I got an "ERROR 2"  
Anyone have a clue?  Thanks in advance!

..I think it might be 'irregular or unexpected drum rotation speed'... and my brain is telling me that Servo Error 04 may be capstan motor, but I'm not 100% positive, so remove the cover and visibly check for drum rotation, and capstan rotation also.

Correct capstan rotation can be confirmed by going into 'shuttle' mode and confirming that slow shuttle-forward/shuttle-backward is happening, since those are capstan & pinch-roller driven functions.

Make sure there's no tape being 'snagged' on the head drum; -it happens with cold tape, because condensation forms on it, and causes it to 'grab' at the surface of the spinning drum.

...oh, and if anyone wants a DA-30MkII, I have one last one of my three PERFECT examples. -The other two have been snapped up, so I only have the one now, but if anyone wants one that can be GUARANTEED to be in full working condition, get in touch... this is the last one.

Of course, you can be assured of an EXCELLENT maintenance history, but I now no longer use DAT... even though I'll still be keeping one DAT player... an Uber-rare in-dash Sony DTX-10...

Hey Guys!

Firstly, I just wanna say thanks for this excellent thread!

My DA40 was recently stuck on Error 1 & wouldn't load or play.

After replacing the small belt with the MCM variety mentioned above, the machine will now load ok. Play,stop, and shuttle (forw&rev) all work ok.

However, FF and REWIND do not work . On pressing either FF or REW button, I can hear a motor spin up to a VERY high speed , but the spools dont move..  I can stop the motor spinning by pressing the stop key.

I have no service manual , so I'm not even sure which motor is responsible for FF/REW , but it does seem like something is maybe not engaging in the transmission somewhere, and when the motor is activated, it is just spinning, unloaded, at max speed.

Any thoughts on this, Anyone?  Is this still a loading belt issue, or does it sound like a problem elsewhere?

Many Thanks!

The FF/REW is handled by "Mickey Mouse".

...Seriously, there's a set of gears in there that looks like the Disney corporate 'Mickey Mouse' icon, with the large circle and the two little 'ears' on top.

It's located in between the two tape hubs, on the deck plate.

The larger toothed wheel (...let's call it a 'cog') is driven by a VERY small cog on the motor shaft, and it has two "ear" cogs attached to it. The set of three ('head' and 'ears') are all mounted on a 'slippy' post, which allows the whole head/ear assembly to 'lean' one way or the other.

When it 'leans' one way, one of the 'ears' meets the toothed part on one hub; when it 'leans' the other way, the OTHER ear drives the toothed part on the OTHER hub.

The motor spins fast, spins mickey's 'head' (and associated 'ears' and the idea is that the rotating friction (which provides an opposing force) causes the whole head/ear assembly to 'tilt' (or slip) towards the required hub.

Now...

Over time, the post/shaft on which the assembly 'slips' itself gets a little sticky/gummy, and the unit doesn't engage with either gear.

The repair itself is not too complicated...

...HOWEVER...

GETTING to the repair is a pain in the butt. -There are a lot of small, fiddly and delicate parts which have to be removed on most transports... I don't know the DA-40 intimately, but I'm basing all the above on the assumption that it works the same way as all the other TASCAM transports which I do have to work on...

I just looked at a DA-98HR which is open on my bench here, and it too uses the 'Mickey-Mouse' method of engaging fast wind.

The main 'head' is hidden under a dress-plate, but you can see the 'ears, and using a toothpick or something similarly non-scratching, you can wiggle them from side-to-side. THey should move VERY freely.

If they don't, the shaft needs the 'gum' cleaning off and then re-lubricating; it's a pain in the butt to get to, and there's the risk of losing some of the VERY tiny parts, like the little 'split-clips' on top of the shafts, or one of the infuriating little spring clips (the back-tensioning arm assembly has to be dismantled to get the plate off...)

So my suggestion would be to take a look to make sure that while you were changing the belt nothing untoward got lodged in without you noticing, but if it just feels sluggish and 'gummy', then I think it would need professional attention... which may cost more than the machine is worth.

-If you have an absolute need for a DAT machine in order to transfer archived material, I probably have one which you could have for a lot less than the cost of dismantling that transport... it might be the better option.

Take a look though, and if anything differs from my description, photograph it and let me see if anything else springs to mind.

Hey Keith..you're a star!

I gave mickey a wiggle with toothpick as you suggested.

Seemed to be quite freely moving...tried a DAT in there , and this time FF/REW worked properly. I did nothing else!

I can only assume that your assumption was correct about some fragment of dust etc getting in there during the repair period. The unit was sitting out for a few days waiting for a belt to arrive, with no lid on , just a plastic dust cover loosely over the top. Also , this FF/REW problem only appeared since opening her up...

Everything's running smooth now. I'll keep checking in the next few days and monitor how she behaves .

Many thanks again for that very useful explanation!

BTW: Love the in-car dat machine!

Cheers
