Here's the schematic. I have one of these amps, I'm in the process of converting it to a SSS type amp. Good luck on your repair. Let me know if you need any parts from my preamp board...I'll not be using it!

Put some more work in on the Matamp GT 120 project. My wife had some unexpected surgery, so I've been otherwise occupied, but things are much better. I may need to mount a hoist above my bench to finish this beast!

Cool! Nice start Darin. I'm about to start my Frankenstein SSS since Aaron posted the link to his 300SL thread. It's exactly what I was looking for.

I'll be following your build with interest!

Mark

Hi Aaron,

That's exactly what I was looking for! I'll hopefully be able to start this build soon and I'll report back in this thread.

Many thanks!

Mark
