Zenith 9-S-262 Restoration Chronicles
#16

Per morzh's tip above I changed my mind on leaving P/N 22-571 alone and just using lugs to wire in replacements (Thanks morzh!!!). I've come this far so I thought I might as well do it right. This electrolytic capacitor has three capacitors inside (C19, 2 mfd, 450V / C20, 6 mfd, 200V / C21, 8 mfd, 450V). The replacements were all the same value and all 3 are rated at 450V. This is the can they go into. I inserted a screw inside the bottom so I could have something to grab onto:

I thought I may have to heat this with a heat gun to soften it up enough to pull out but it slid right out without it:

Here is the replacement I made to place inside:

I used hot glue to hold it in place inside the can. I didn't use too much. I wanted to make sure the repair was clearly visible and I wanted it to be easy to remove for someone who may have to work on this down the road someday:

Here it is after installation:

Here is a photo of the other electrolytic (C18, 12mfd, 450V). I cut the can as close as possibble to the bottom, cleaned out the inside, inserted the replacement, and then used JB Weld to to put the 2 pieces back together again. The repair left a visible line where the JB Weld was so I wrapped a small piece of muffler tape around it. It turned out better than I thought:

The wiring of the underside of the chassis is about 95% complete.

One thing I'm going to have to spend some time on is the Dual Fixed Padder (C7). As you may recall from my earlier posts I totally disassembled and cleaned this. Here it is before cleaning:

I've been given tips on how to align this after everything is back together. But I checked the continuity between the upper and lower left side lugs. This should not have continuity but it did. Same on the right side. So I'm going to have to spend some time and take this apart again and see where the opposing plates are touching. Shouldn't be a big deal, just tedious.

Well, that's all for now... stay tuned and thanks for following along!!!
