This is something I should know , but it seems to have escaped my memory
bank. !!
I have several 811A's and all of them have oblong shiny spots on the
plates, and they all glow a dull red under full power in an AL811 amp. Are
these tubes defective ?? I was running about 70 watts input and about 600
watts out and all of the tubes show the same symptoms. !!! Thanks for any
replies.
