I could really use a picture of the chassis wiring for a 40-88. I’m having difficulty reading the schematic and I didn’t take pictures when I began replacing bare wires and especially from the on/off volume pot. Any reference pics or info would be appreciated.

I think they all come from the same place...

The power switch is pretty standard fair for a battery set. It disconnects the A+ and the B+. This insures no battery drain when the set is off.

figure out what all those squiggly meant.

Now I think I've got!
