Hello all,
i built a yu1aw 2 meter gs-35 amplifier about 8 months ago. been working great.
just recently i can here my voice coming from the cavity. also the tube seems
to be glowing a much brighter blue than before. with the lights out i can not
see any arcing. the amp is running the following
plate voltage 4100 no load
plate voltage 4600 full load
plate current 1.0a full load
bias -30v
output 1450 on diawa cn801hp
any ideas would be appreciated.
Carey, kc5gtt
