Apt Holman repairs


I own an Apt Holman preamp, circa 1980, designed by Tom Holman. There used to be a few highly reputable repair companies that upgraded some of the components in these preamps, along wtih performing expert repairs. Does anyone know of any such companies?

A vote from me for Audioproz.
The owner and head tech, Vince, worked for Apt-Holman ( mine had been originally signed by him) and he has a few upgrades he does during repair.
He is an interesting person to deal with, not much for fuzzy, warm small talk but has repaired an array of things for me and always done a very good job.
