Working on a better PCB schematic, may as well, since I'm probing continuity.
Trying to label components, and add lines, colour schemes.
Will I finish, probably not, should just lift the board, flip it, check for bad solders, take a pic, flip the pic, and draw components on the pic?
I really don't want to lift the board, then I will worry about stressing other wires, and break solders.
I'll just keep probing, it just helps to know where to go, luckily with a flashlight a lot of the copper foil lines are easy to see.
By the time I fix this rig, I'll probably be able to build my own amp.
Going to do some major probing on my days off.
