Hi again.  An engineer friend of mine is trying to look at my amp.  Has anyone had any hands on experience working on one of these?  Any source of information other than the original schematic?  Any input would be very much appreciated.

Thanks, Ray

Hi!  I recently picked up a Kay model 708 amplifier.  I believe this was one of the first SS amps.  Problem I am having is the vibrato thumps all the time and the controls  have no effect.  I have the schematic for the amp.  Not sure where to start on this.

Thanks for you assistance.
