Guys,
I am re-purposing a Session 400 power amplifier from my junk pile. The circuit board was fabricated 8/77 - I noticed the protection circuitry is a little different than the 10-24-74 schematic I got from Peavey. I have a couple different schematics but none of them match the circuit board.
To be clear I fixed the amp, and it works great. However, I think the protection circuitry is not loaded right and likely not working correctly.
Do any of you have a newer schematic or layout for the 8/77 circuit board.
Many Thanks, Jerry |
