I now might agree more with John Freau on the gap cooling issue.  High power
demands real cool gaps.  A condition which mimes detuning can manifest
itself with super hot gaps.  If your caps are WWII vintage they are poor
caps and rather lossey provided they are not micas.  Paper caps change value
when heating and the effect is particularly severe in series strings of
larger units.
