I have always assumed that the plates of the stator and rotor of a tuning capacitor should never be shorted. Now in looking for problems on a current PT2 project, I find the oscillator section of the tuning capacitor is shorted. After careful inspection and not locating plates in contact, I back checked a couple other sets I have on the bench and find that they all have shorted oscillator sections.
I must ask, what's up?
