gang..
Haven’t use this amplifier is years, but with the crappy conditions during CQ
WW. I fired the beast up.
It wasn’t a good day.
The amp’s drawing too much current. I’m getting RF out, but not like it should.
On 160 meters, 570ish watts into dummy load
80 and 40, lucky to see 312 watts
about the same on 20
and only 225or so on 15 meters
The tube, all of them, have nice red plates———not good!
160 meters, no red plates and current seems to be within limits.
Grid current about 50 ma on all ands
resting current, no drive, 80 ma.
Not an amp person, so up for some clues
I’m Mike, WB8VGE
