Audio research mod

In the past I have had several Audio Research components modded by Great Northern Sound. Since GNS has gone out of business is there another business out there that mods ARC components. I really liked the work that Steve Huntly did and miss him. I'm thinking of buying a used PH-7 and have it modded.
Give Underwood hifi a call. If they can't modify it, they probably know someone who can.
