Audio Research Reference 3 Seeking help

I would be most grateful were any AG member to be in a position to advise me as to what voltages / loading ARC run the 6550 within the Ref5SE power supply circuit,
as It would seem that ARC Central forcibly lobotomize (other than their official service tech's ) anyone outside of the Program found to be in possession of 'Company' information of this nature !

Tsushima ... respectfully, don't you think that ARC is within its right to be discreet with the type of technical info that is the subject of the last posts. Seems to me that ARC, or any company for that matter, has a right to keep proprietary information out of the public domain if it so chooses.

Of course, I suppose that if one is so inclined, they can buy a Ref 3 or Ref 5SE and reverse engineer it. Of course, that may cost the curious $13K MSRP to but a Ref 5 SE as the price to sate their curiosity.

@Bifwynne
I have dealt with Chris Osanna several times over the years when I brought in ARC gear and every time he was a rude prick!

Where do you live? Not in the Twin Cities. ARC does not send out service techs to anyones home.

ARC has no service techs outside the factory. Store service techs communicate with ARC, but they are independent hacks.

Don ... obviously we have very different views about ARC and some of its people. We will just have to agree to disagree.

Don, I am a warranty repair station for ARC and I find you comments to be rather offensive. I am not some independent hack. I've been fixing ARC gear for more than 20 years and was friends with both Nancy and Bill Johnson. Last year I drove over 100 miles to fix Nancy's Ref Amplifiers. I deal with Chris Osanna on a regular basis and he's never been rude to me. It's possible he was stressed out when you spoke to him or maybe you were rude to him. Given your broad brush name calling it wouldn't surprise me.
