Looks to my unprofessional eye to be 100% stock. Just looking for confirmation from those

with a more discerning eye.

Getting ready to replace the Filter caps and install an effects loop in the two extra speaker jacks.

First glance stock as my cock. Ive had 2 / 1978's my favorite year. My Frieidman KS is a 78. She was pretty tired as a donor amp.
Be sure to replace the bias filters on that. Someone that will flip the board and do it right and not Fuck it up. I had Dave replace my coupling caps per his preference [chicklets] but not mission critical. If you have to tack weld them so be it.
If you're doing this yourself be cool solder / de=soldering the traces they burn pretty easy. 50 yr old board.
Congrats.
