[Boatanchors] Tuning Capacitor Air Gap Information

[jeremy-ca]

A scope works wonders for measuring peaks.

You ever wonder why ham SSB amps often have bad habits of arcing the Tune 
caps? Cheap manufacturers use spacings that equal or just a hair above the 
HVDC and have no overhead for peaks. Thats just for SSB, imagine what 
happens with plate modulated AM.

I get customer amps in here on a regular basis that I have to either change 
the caps or rebuild the type that use removable plates.
