Well, I took the screws out and it did slide out of the case.
I took some photos just to have some reference in case something gets screwed up and forgotten.

Also it is a good way to notice right away what could go on missed or noticed much later.
Like in this case a bent variable cap coupler.

I will put the photos up here tomorrow, now's late.
Will need the sch but this I think does exist in several places.

The very first resistor mounted on a switch I tested was right on the money so it gives me hope I might only need to deal with electrolytic caps. Provided the power is good. The eBay photo shows front panel light on which again gives me some hope the power might be OK.

Well.....here goes nothing.
