Belles 21A standby mode?

1markr, I received my L-2 Christmas day(actually arrived). I'm very impressed with it and feel it was a definite improvement over the L-1 I had previously.
Why don't you call Dave Belles and talk to him about your questions. I would think that it would have a standby mode that at least keeps the filaments heated like the AI.
Let me know about your final decisions on the preamps.

Maybe this an apples to oranges comparision...
I also have a Belles 20A, plugged it back in, power swich off and there is a faint glow on the filaments. When powered on, the glow reaches the intensity that I see with the 21A powered off.

Jmann....have you gotten any further details or information re: the tubes in the 21A and the standby mode? My emails have not been answered yet.

Turns out to be a non-issue - 21A is operating fine. I have the option of sending it back for a checkup if it makes me feel better. Sorry for all the commotion.
