Quiescent current of B-2
Excuse the resurrecting of this venerable thread, but I thought it better than starting a new one for a trivial-seeming question.
Does anyone know the idle current of the B-2? I want to get a handle on how much heat will be generated at idle, and whether I wil need to switch off when I'm not using it for monitoring in my studio. I have one on the way and may need to adjust my equipment arrangement to deal with the heat.
The thermal shock of inrush current concerns me, but I read somewhere that some amplifiers do not like to have inline rheostats to make the powering on gradual, so information about that aspect of the B-2 would be welcome, too.
Thanks.

I think what you actually mean is a caring, competent technician who can give it a good going over replacing capacitors and cleaning switches and possibly replacing the speaker protection relay. Would that about sum it up?
You're looking for an older technician who probably works from home now and was active in audio service from the late 70's until at least the 90's as a minimum "spec". That person will probably not work on TVs, monitors, VCRs or video in general. Probably not a PA amp guy either.
That amplifier probably just needs some intelligent TLC. There has got to be someone near you who fits these qualifications.

Hi Herman,
Sorry, but the only person I know in Chicago isn't a technician and probably wouldn't want to work on it. I wish I could suggest someone to you, but being in Canada takes me out of the loop.
You have a really special amplifier, so you've got to be extremely careful who you allow to work on it. Yamaha's service department is good up here, how are they in the 'States? It might be worth a try.
