I don't see a Sams at the ETF. Do you mean the Motorola service manual ?

Yes, if that cap was defective I think you would have low B+ but probably not ripple. Make sure you have it installed with the correct polarity.

That cap is part of the B+ voltage doubler and has a fair amount of power going through it. Ideally, you want to use a low ESR type rated for high ripple current. That's more important than a high voltage rating in this application.

It's kind of hard to find, you have to look for this model of TV. If you look for the chassis "TS-14B" they only have the service manual with it, and that schematic was just as hard to read as well

That cap is installed correctly. You say up above, that if the cap was bad I shouldn't have ripple(is that the technical term for a moving (still) image?). Yet below you mention that the cap should have low ESR(I don't know the specs when it comes to that) for high ripple current.
If that has high ripple current going through it, how would it not get past the cap, if the cap were bad?

Hey guy's, I found that I still have a few caps that look like wax paper caps, but are real low value. Lower than what I have for the standard replacements. 2 are in the tuner circuits and 1 is elsewhere. I'll get a pic up in a bit, but should these be replaced like normal value caps?
Could they be causing any of my current issues?
