[Amps] Centurion problems....

[john]

I've had a recent failure with my Centurion... was operating it about 600 
watts out, when I heard a "TICK" noise (sounded mechanical, not electrical) 
and noted that output power dropped. Plate voltage was still normal, but no 
indicated plate current).

	I happened to look into the grill on the top and the PA plates were red.

	Turned everything off, then back on a day later,  at first all was well, 
then the same thing happened again ...amp was normal, then output power 
dropped to exciter levels, and the plates began getting hot as 
before.  I've looked beneath the sockets, and nothing seems to have gotten 
too hot here (or anywhere else)

	Ideas?
