>But by no means am I a tv repair man
That make two of us. I have fixed couple of dozen over the yrs.
>Also does your average DVOM have enough power to get a cap to charge?
Short answer is no. Long answer:
Irrelevant as you need to check leakage which requires to apply a voltage close to the maximum rating in parallel with the cap under test and measure the series current. Should in the low micro amps if good. Generally not worth the effort to test just to find your 70yr old cap are junk. As I posted b4 replace the foil/paper and electrolytic caps. Leave the mica and ceramic caps, fail rate is low on these types.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
