Excellent job Ron! The springs can be a little tricky if you don't put them back exactly where they came from and in the proper orientation. It can interfere with the action of the leaves. Also, when the leaves close, they smack against a hard stop. There was originally a piece of felt glued there to cushion the action. Over years of continually changing bands and smacking the leaves against the hard stop the felt can get worn down. I replaced the felt on mine with some self-adhesive felt cut to size.

I remember there was one part on my 9S262 that I goofed up on during my refurbishment. I'm the type that likes to take everything apart and clean everything down to the last nut and bolt. Here are some pictures of P/N 22-558 (C7 on the schematic).

This was covered with what seemed to be a light oil and it was very filthy. So foolish me, instead of just wiping it clean I totally disassembled it, cleaned it, and put it back together again. I assumed that this padder was covered in the alignment instructions and I would just reset it when I was done. Well, guess what? It's not. And I had a very difficult time trying to put it back together. I broke a few of the mica sheets. I bought some replacement mica sheet but it was too thick. I tried to shave it into thinner sections but didn't have any luck. I finally gave up on it but luckily another forum member was kind enough to send me an original C7 from a parts set he had.

That part was in the Zenith Parts Catalog I linked to in post #12.

I never really understood that if the capacitance in each section was fixed, why have it as an adjustable padder? You would think they would have just installed one 1500 pF cap and one 5000 pF cap and been done with it.
