I have the same preamp, just acquired from a friend. Mine has the extreme mod package loaded up with Vcaps..... These mods were performed by Response Audio out of NY. Wonder if you can google for the link. Maybe they can help. I've owned numerous tube preamps - TAD, Audible Illusions, Counterpoint, VTL. This modded MC-7R betters all of my previous preamps. Get yours fixed and hold onto it. It's a keeper
Ming MC-7R repair
Is there anyone who knows a shop that can repair the Ming MC-7R other than Pacific Valve? I know there was a place in upstate New York that modified the unit with better caps, etc. but I've lost the website. I really like the unit and have invested money in some great NOS tubes but the ability to service it is below par since it only works through an email contact and takes days to get a reply. No phone contact with Pacific at all. Any help?
