Anyone want to trade a 1/2" callibration tape for a TASCAM 22-2 headstack ?

Hi,

This may be a tall order but here goes .... I have a headstack from a very low use TASCAM 22-2 (will also fit other models) and rather than selling it, I thought someone here might be interested in trading it for a 1/2" callibration tape. It doesn't have to be a proper and original MRL tape. In fact, that would be crazy as those things do cost quite a bit and it wouldn't be a fair swap. I just need several basic frequencies at 0dB, 250 nWb/m, IEC EQ, 15 ips, recorded on good tape on a well callibrated 1/2" 8 track machine such as the TASCAM TSR-8 or TASCAM 38. It's for my newly acquired TASCAM 58-OB. I'm broke. :(

I can post picts of the head stack if anyone is interested. I estimate under 100 hours of use.

Thanks,

Daniel
 
I just might be interested in this. I have a 22-2 that could use a new headstack, a tascam 38 that was calibrated two weeks ago, and some new quantegy 456 tape. If you can tell me how to get those signals onto tape you've got yourself a deal ;)

EDIT: I just realized it's a 32-2 and not a 22-2 I've got. and I was so excited for a moment. oh well.
 
It's good of you to offer and I really appreciate it but two things ... (1) I was already offered a callibration tape, which is on its way .. and (2) This was not a trade and so the heads stay with me, at least for now. ;)

I think you're right that the heads may not be compatible with the 32. The site http://www.openreel.net/parts_2.html has listed only the BR-20N, 32, 33-2 as sharing the same heads. It seems the 22-2, from the same site, shares heads with the 32-2B and the 35-2, from the TASCAM line and several other TEAC models. I wonder if that's true ... :confused:
 
A 58-OB? Man, you jumped off the deep end!!!

(I told you a long time ago you'd end up like this!) :eek: :eek: ;)

Hehe! :D Yeah, I know, I know Dave .... :o

.....and the 58-OB is a bloody rare item from TASCAM and can you believe very low use, with original binder manual and local too!! :eek:

....had some problems that I used deoxit to cure. A couple of frozen meters, signal not coming in too well, from the RCA jacks (also has XLR's ;) ) but sprays of the deoxit into the jacks made it good again.

... I also found some hissy channels which tend to go away after the machine is warmed up a bit (anyone know what it could be ?? :confused: )

...... All in all a very low use machine, which certainly is a reason for the issues outlined.

Records and plays back beautifully though.

....I hope to post some picts soon. :)

It's hard to say over the net with these kind of issues? Aging caps would be my guess.

If it does go away after the machine is on for a while then I guess you've found your work-around. ;)

Generally, it's a good idea to turn on your recorders and mixers for a good 30 minutes anyway before doing any serious work on them, especially calibration adjustments...the manuals mention this as well.

Congrats on the 58! That's a sweet machine...built like a tank too! :cool:

Cheers! :)
 
To be more precise, it is only when I roll tape and monitor from tape that I initially get left side hiss, no matter which channel(s) I'm monitoring from. The hiss comes on and off and goes away after maybe 20 - 30 minutes. Yeah, I'll definitely warm up my machines from now on.

Do you think, if it is infact the caps, that they will come back to life (more or less) if the recorder will be powered on for at least 30 min every few days or so ? Thanks Jeff!! :)
 
Daniel, the problem you now described sound more like a mixer issue?

Either way, the same warm up ritual is applicable.

As for reconditioning the caps by exercising them, I think that might be possible so long as their only marginally weak but then again, we don't know for sure if it is the caps? Other electronic components can also behave differently at different temperatures such as resistors and IC chips so it's only a guess on my part.

There are freezing sprays that technicians use to find thermally defective parts but in any case, I'd wait for a total failure before ripping stuff open.

Cheers! :)
 
I definitely will not be ripping anything appart! ;) I have nothing major to complain about, really ... I will check the mixer, however. Thanks again Jeff! :)
 
Electrolytic capacitors can 'reform' if used, but I've only heard of this done with high voltage parts (e.g. smoothing caps in valve/tube equipment).

Replacement, especially for low voltage caps (which are cheap) is probably a better option.

Some info about reforming electroytics here. Note that the circuit here is for reforming high voltage caps (> 275V) and is quite dangerous!

Other caps you'd probably find in anything less than about 30 years old - mylars, polyester, disc ceramic etc - should still be ok.

Other things to watch - carbon resistors can get noisy and dry joints can be a pain.
