Got the CTC11 chassis out and on the bench. Everything looks pretty good. Pretty much untouched except for some previous work on the "C1" electrolytic can. It was wrapped with lots of gooey electrical tape... Took the tape off and found the cardboard tube has split open sort of like a can of pillsbury biscuits.
Then found an old Sprague Atom cap piggy-backed to C1 from behind. Not very pretty repair work.
There are also several Sprague caps that sort of resemble orange drops, but have a flat, chalky look to them. Do these tend to be reliable?
The inrush limiter is broken, which is not surprising. I'll replace it with a CL80 or similar unit.
I am still temped to go ahead and replace the purple film caps and the other orange caps along with the electrolytics. Still thinking about what to do. I'd prefer not to disturb any circuits that require any kind of alignment.
