Default KAT88 playing up circuit diagram needed

hi.

I have a Kat88 power amplifier that seems to be going into oscillation with all speakers.

My repairer, Henry, needs the circuit diagram to do the repair.

Does anyone here have one? Thank you!

David

Hi David,
Looks a nice build from a while ago. There were one or two changes early on but yours looks to have included them. Has it just started playing up? 1 or both channels, HF or LF or a hum?
Send me a PM with your direct email and I'll send the info you need.
