AUDIO RESEARCH D-76A

Hifigeek: I know this is about Torogis' amp, not mine, but I'm just curious about how much it costs to refurbish an old amp like the D-76A. Reason: one day I may have to refurbish my VS-115. Thanks

Dear Torogi,
I don't see where you say you have any problem with how the amp sounds. It is highly improbable that it could operate properly if indeed those tubes were not firing up. It is often difficult to see the glow from a tube; have you looked at them in a darkened room at night? I suspect that you have no problem at all. Or is there something perceptibly "wrong"? If so, what?

Hey Lew, on 4/3/11, Torogi says that the amp has tsouris in the right channel. It seems like Torogi may have bought a refurshing.

I tried turning off the light to see if its lighting up and I also tried touching the tube with my bear hand after two hours of the amp being turned on. I know I'm not suppose do that but I can't stand the fact one of the tube is not working. right now I cant barely hear the right channel so I stop using it. I entent to keep this amp for a long time so I will fix it or have it fix regardless.
I dont know why? may because the first time I use it with my vintage JBL it sounds warm and sweet. before I had that problem. by the way I live in west coast of British Columbia. Vancouver BC. how far are you from BC HIFIGEEK1?

I'm in L.A.
