AUDIO RESEARCH D-76A

I think the D-76A has a line fuse but not a screen fuse. Do we know if it has the right line fuse in it?

No, nor do we know who told him it didn't matter whether the tubes got hot, nor whether he heard any music, but I guess his using it means that.

I'm not sure whats the deference between the line fuse in the screen fuse. all I know is that the D-76A has a line fuse. its rated at 6 A 250 V How do we find out weather its the right line fuse? surprisingly it never blew. I will try my third attempt tomorrow to call CALVIN at ARC to ask some of this questions.

Torogi, your last post implies that you are having a hard time getting through to Calvin. That is surprising because he is always available, at least when I call. I know he was on vacation last week, so perhaps he's catching up. If you can't get through to Calvin, then try Chris. Chris is the resident techie at ARC. I know that he supports the local ARC authorized repair guy where I live.

Sorry to sound like an old saw here, but I agree with Hifigeek and the others who have recommended that you ship the amp off to either ARC or an authorized local repair tech. I get the sense that you are trying to trouble shoot the amp yourself and unless you have a deep technical knowledge of electronics in general and ARC gear in particular, I think you're literally playing with fire, IMHO. If it was my amp, that's what I would do.

Your not going to get the answers you want talking to Calvin as he is the parts manager. Chris is the tech and he wont be able to really answer you because the unit is not in front of him. I can look and see what the fuse is supposed to be but that still wont solve your issue with the tube and the non standard ARC parts that were installed. It will have to go to someone for repair. You can send it to me or to ARC. Either way you will need a shipping carton if you don't have the original one for that amp. The boxes are not cheap but its the only way that amp will survive it's journey without damage.
