Identifying guitar tone control capacitor

[dirtgeek]

I have an old Decca guitar from the 60's with this capacitor that I'd like to replace, but want to make sure I'm identifying it correctly. Lots of old codes out there.

The picture isn't super clear, but it reads the following:

nichicon
.02(K) 50

Would that be a 20pF, 50V cap? Or does the K mean something else?

Also, this is some sort of poly film cap, correct?

probably 0.02 microfarad. K is 10% tolerance. 50 is 50 volt.

Film of some flavor, probably mylar.

I agree with gadget. Guitar tone caps typically range from .015-.047 mfd. There a a few exceptions though. Id love to see a pic of that beast!

Agree, .02 uf 50v rated. I doubt you hear much by changing it . It’s still good . They don’t see much voltage and it is not an electrolytic.

Great, thanks all.

Picture of the beast. It's in rough shape, zero fret is missing so you can't play in tune, and all I get is a few crackles when plugged in. Currently it's in pieces as I'm cleaning everything. And instead of putting in a zero fret I'm moving the nut forward.

Zero Fret is much easier to install. And the Height of the strings will be much easier to get right.
