hello all,
developed a problem with my amp. with a dead key no signal in the tube starts
to get VERY hot. nothing has changed in the amp. i have tried 3 tubes and they
all seem to do the same. they also do not tune up past 1200w with 100w +/-
drive. the idle current also is high on the meter for amount of bias i have. it
takes 56v to get it down to 100mils. had been working great for the past year
or more.
2m gs-35b yu1aw lazy builder
4100v plate
29.8v bias = 250mils
Carey
