[Johnson] Invader Problems

[David C. Hallam]

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?
