Steve:
I have a K200-A5 with a dead reverb driver. A schematic would be very helpful to me as well...if you have one.
Any possibility you'd have one in electronic form, and could e-mail it to me?
For that matter, if you have any suggestions where to look for problems, I'd be grateful for that as well. The reverb return pre-amp works fine...I can tap the tank and get plenty of thunder-crashing.
I'd also like to improve some of the components in this amp to get rid of the hiss. I've heard it can be done.
BTW, your posts here have been very helpful to me!!!
Thanks,
Dave O.

Yes, I'm getting no drive to the tank.
I have 4 or 5 reverb tanks, and I'm quite sure they all work just fine. Measured the drive voltage to the tank, and there's practically nothing showing up there...even with no tank connected.
Does the remote foot-switch have anything to do with the drive to the reverb? I don't have a foot-switch. My problem could be there...but without a schematic, I'm not really sure what's going on.
Where do I find a schematic for the K200-A5?...or one that's quite similar? I haven't seen one for that head yet. Perhaps I'm just not looking in the right place.
Thanks for the tips on the transistors...I'll try that for hiss reduction.
Sorry I've been so long responding.

I'd be very greatful for a copy of that Schematic!!!
573--243--6266
Thanks for the other tips too!!!
I have bunches of 2n3904's...but I was thinking that a cap had probably dried out.
I'm a broadcast engineer BTW...been doing that, and playing bass for more years than I'd like to admit!
Thanks again,
Dave O.

I'd give that thief 24 hours, and then call the police!!!
It's those kinds of places that give all techs a bad name.

the police could care less, the people who would really want to know is the better business bureau, they would be the ones to do something about it
