Hello all,
I have a TL922A with all the Kessler Engineering mods that was recently put
into service. I've noticed the amp is generating a lot of heat while not
transmitting, in fact in the CW position, it's drawing 100 mils IP. I don't
remember the amp pulling this much current when just sitting there before,
but perhaps I was inattentive. It has normal power output and tunes just
fine, but the heat is significant.
Shouldn't the resting current on the tubes be 0? Is this an indication the
3-500Z are failing?
Thanks,
Natan W6XR
