[TenTec] Hi power Ten Tec ant tuner swr drift?

Depending upon how often the network has to tune an impedance with a 
very low R component, it may be worth the effort and expense to replace 
the ceramic disk caps with something more robust, like an HT-50 series 
doorknob component.

Back when I had my 229, I replaced a smoked cap (by previous owner) with 
a doorknob.  I also attached a 1000 pF unit to the "auxiliary" cap 
terminal in order to be able to radiate *something* on 160 with my "cut 
to fit in the yard" 110' inverted vee.

Granted, I never ran over 100w, but never felt any evidence of component 
heating.
