?  New to my Web site is a photograph (see Figure 15H) of a Henry Radio 
Co. amplifier's bandswitch that has a damaged contact and rotor.  .  In 
my opinion,  the damage resembles arcing caused by intermittent VHF 
parasitic oscillations.

?  I doubt that the parts in Henry Radio amplifiers fail solely because 
they are defective.  A case in point:  The Eimac 3CX1200A7 has roughly 
5-times as much feedback-C an an 8877.  The A7 has a well deserved 
reputation for oscillation.   I have talked to a number of owners of 
Henry 3CX1200A7 amplifiers who have experienced mysterious, intermittent 
bandswitch arcing.  Eimac apparently realized that there was a problem 
with the design of the A7 and redesigned it.  The result was the 
3CX1200Z7, a tube which has 1/10 as much feedback-C as the A7, and costs 
only about 5% more.  The Z7 has been available for at least two years, 
however,  Henry Radio is still using the A7.

Appealing to personal considerations rather than to logic or reason: 
Debaters should avoid ad hominem arguments that question their opponents' 
motives. .  (American Heritage dictionary)
