Title: Marshall origin 20
Post by: seth pittham on August 02, 2021, 11:54:57 am
Hi guys. Anyone have a schematic for the above. I have one in with low gain. All valves good. There seems to be lots of silly relays and stupidity around the board.
Cheers

Probably need to contact Marshall for current production stuff.
