[TenTec] Ten Tec Centaur issues

[Mike Bryce]

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
