[ARC5] BC-946 capacitor plates shorting?

Well, not to be too obvious, but if you suspect shorting, it’s best to test that hypothesis, say, with an ohmmeter. Then proceed from there.

When I tune up, or down, it mostly goes quiet except for scratchies (is that a technical term?) noise.  On close inspection one of the rotor plates may be touching a stator plate, hard to see and tell.
