I wanted to thank the many individuals who took the time to offer
insightful suggestions about the problem I was experiencing when I turned
on the Henry Amp and it without excitation was drawing current. I made
all the tests suggested and still the solution eluded me. At that point
in time, on the high end of the exasperation scale, I realized that I was
probably looking in the wrong places. Although I'm embarrassed to admit
it, I prove unquestionably the age old adage is absolutely true that
none is so blind that has eyes and see not! Buried under one lead of a
filament voltage thru chassis fitting, I noticed a .01 mfd bypass
capacitor that I didn't even know existed. Obviously, I also came to
an immediate realization that this almost inconsequential charred
component (that had apparently exploded) was in need of replacement. Sure
enough, it was welded closed and it exhibited a dead short to ground.
In any event, all's well that ends well when it was replaced. The Henry
is up and running and as happy as any inanimate object could be. Thanks
again for all your thoughts. It's greatly appreciated. Keep in mind that
the one filament leg, although grounded and without HV, apparently was
still able to light the filaments without even a hint of a problem. Best
regards, Ron W2CQM/3
