[Amps] Ameritron Al-1500 excessived grid current & shut down

[Herbert Schoenbohm <herbert.schoenbohm@gmail.com>]

Today I turned on the Al-1500and immediately notice that the grid current
went all the way over to the right and the amp grid protection circuit kick
in.  Even with only 5 watts of drive, the grid current is about 175 ma.  I
also notice that I don't see any HV indication.  I hope this is not a bad
8877 final tube. Any suggestion to confirm this would be appreciated.

Thanks,

Herb, KV4FZ
