Found noisy Cryo'ed EH 6922

Tubes Asylum

Questions about tubes and gear that glows. FAQ

I thought it was kind of weird that the noise was constant in all channels. Definitely took away the magic of the pre-amplier. Finally opened up the Anthem, all 18 screws! Replaced the tube with it's predecessor, a Tesla -- possibly a step back sonically from what I had had before. Happy now ;-) Although, the magic sort of disappears as the last screws are torqued on. I really suspect metal covers are detrimental to the sound of components.

Anyway, I never thought that one tube would distribute it's noise to all channels and tubes. I suspect it was the filament, whose circuit is basically common to all tubes. I wonder what the noise mechanism is??
