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
output 1450 on diawa cn801hp
any ideas would be appreciated.
