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.

You can get schematics from this site.
Replacing the first and second gain stage transistors in both preamps with modern lower noise items helps the hiss problem. ]]>stevem2007-01-08T12:05:16-00:00Re: k200-5 schematic

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.

The PC301 board has one transistor(Q301) driving the pan thru a 10 MFD electrolitic cap.
The original 2n3565 transistor crosses to a nte123, or a 2n3904 that you can get at any radio shack location .I would just replace that transistor and That C301 10 MFD cap, as that cap itself could be bad and doing in the drive.
Their is also C309 cap, another 10 MFD that could be bad too, that is located off the center tap of the reverb control.]]>stevem2007-01-22T17:54:52-00:00Re: k200-5 schematic

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.

It's those kinds of places that give all techs a bad name.
