Subject: Failing tube symtom

Hi all:=20

What are the clear symptoms of failing tubes?=20 Is 1 of them when you have
your plate and load adjusted for initial max = output and each time after
that, the output gets less and less?=20 Will a tube just go like a light
bulb, 1 minute you got full output then = boom, no output?=20 I'm thinking
once again about my fuse blowing issue and according to = NC4L, the 102 guy
in FLA,=20 this is a sign of failing tubes because of miss tuning or too
long key = down in the tune up cycles.=20 He calls it thermal run away and
it contaminates the screens and deforms =
them.=20
The only way to fix this is with a new set of tubes, which I have.=20 Well
not brand new but a good set of backups.=20
