what next

[DaveWM]

One of the top hats (mounted on top of the chassis) has corroded off its lead. Will have to dig thru my stash for a power diode before doing anything.

there is also some old looking device that it bolted to the side of the chassis (inside) it looks like some kind of mechanical breaker but I cant see a reset will have to look a bit closer to see what it does. it does connect to the power switch.

going to take a look at the schematic and see if I can figure it out.

some of the pots on the side are nice and crunchy, yuck.
