Audio Research Reference 3 Seeking help

As I explained above .0024 mfd caps will not give you better sound and are not coupling caps. You can try emailing the factory for this information.

You can email the factory: service@audioresearch.com

ARC never used .0024mfd as a coupling cap. I do not know where you are getting your info from. That value is way too small for a coupling cap as well as for a bypass cap.

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.

No sir, I was not....Fixing TV's does not qualify someone to fix complex vacuum tube audio equipment with solid state/tube regulators. It's obvious to me you have had some unresolved issues with service providers in the past and that is unfortunate.
