A'right, I tipped her over to take a look. Unfortunately we broke the "pristine" streak. Someone's been here before...
General overview.
Note the blue wires patched in, those go to the yoke. Probably a repair from when the tube was replaced.
Blast, there were mice. They've nibbled at some of the capacitors, but apparently this one tasted by far the best. I must make a note of that the next time I'm feeling peckish.
Fortunately, the coils didn't appeal to them very much - that's a good thing. I probably had beginners luck with my 4068, but at least I won't have to find out whether that's the case (knock on wood)
There's also a lovely bodge job on a replacement control:
Next step is to photocopy the schematics and trace things out... then I can order up some parts and get re-capping.
I still have a decent stock of resistors left over from my radio job (cheaper to order 5 than just 1, or minimum quantity was 5) so I should be stocked for the bad ones I run into.
In the meanwhile I'll work on the cabinet. Looks to be photo-finish or a print-on of some sort. Top surface is a bit scratched, but should look all right with some elbow grease.
