How do you decipher these? There are no mfd or voltage ratings on them.

I used a reactance calc online, plugged in 900uf at 120hrz came out to 1.5ohm approx, for for voltage I would look at the circuit, that high a uf makes me think its a cathode bypass, so prob low voltage.

Is that cap in a Dumont set? Looks like their part number.

Yes it is, and there's a bunch of them. I want to replace them.

What's the model/chassis number?

Model ra-103 I think the chassis number is 7041-a1
I think I'm going to need a service selector switch, because there's alot of arcing in it. Where's there a good place to get one?

It is low voltage, the can has 6vdc marked on it.

Is it possible to identify them from the SAM's or Rider diagrams?

Sams does not state it in mfd. Horizontal center control bypass is the ID of it.

Maybe C278?

Which looks like a 100uf at 25v.

This is from the TV Rider on the same page as above.

C4, C5, and C6 in sams. I figure a 1000 uf at 25 volts should be ok. Although C6 states 2000 uf.

What are some weird but good common food combinations?
