I bought a bunch of capacitors at a garage sale can I use these in old radios?
The bigger caps that have marking un them that I can understand are too low of voltage for tube radio use but the small caps are marked weird here are a few examples 10k kc k, 65 10% RMC N15CO, 200-k N750 100V, 69 k N750, 200k 100V N750. Can I use these? If so how do I know uf, working voltage? I have a few hundred caps and 200 or so resistors as well. I paid $2 so not a big loss if I can't use them.

The caps may have to be reformed and should be tested before use and yes you can build circuits and repair like equipment with those components.

These look like ceramic caps...69K is probably 69 picofarad, 200K may be 200 picofarad...it would probably be better to install brand new caps for replacements though, as you definitely would know their working voltage and know they were good. Most old ceramic or mica caps should be OK but would not ever re-use old paper or electrolytics.
