This is a somewhat difficult thing to explain to anyone who has not had 
extensive experience with car salesmen.

Do you believe that tubes gas up and fail when they are in the mfg.'s  
sealed box.?

Without such a resonance, there could be no bandswitch arcing.  This 
thread is about arcing.

He was the first who measured the resonance in the AL-80 Tune-C.

Better ask Tom. {chortle].

To produce high voltages, the resonance can not be on the parasitic freq.
