While casually listening from another room, it occurred to me that I had been hearing a hum in the music -- I guess I dismissed it as part of the on line music track . . . for a few minutes.
But thought I'd better check.
The hum was from the right speaker, and the rear right power tube was glowing. I mean, the entire insides were red hot.
I shut it down, and took some temperature readings. The other tubes were rocking along (Well, it was jazz that I was actually listening to) at about 156 degrees. The red tube read at 408 degrees.
I guess it's goose is cooked?
