I’ve read conflicting information on when Marshall switched to cascaded preamp designs. I’m about to pull the trigger on a buddies 1977 JMP 2204 (3/1977) but I want to confirm it is the cascaded design. See below gut shots thanks in advance for everyone’s help.
Also what I’m I looking for future reference?
Anything else interesting you can tell me by these photos related to mods/changes?
