[Johnson] Invader Problems

[Dennis Petrich]

What do you mean by output coming and going?  Please be more specific.  What
is the plate current doing?  What is the High voltage doing?  What is the
grid drive doing, what is the output power doing? And so on....

I have just moved my Invader 2000 to the beach to start trouble shooting on
a problem that has me puzzled.

When I turn the rig on, I have to leave it on standby for 20/30 minutes
before I can get any output.  Then after 2 or 3 hours of operation, the
output goes away.  If I let it sit overnight, I can get output again after
the 20/30 minute wait.

What in the world might take than long to "warm up" before it works and then
get "too hot" to operate after a few hours?
