Red Rose Tube Amp repair in Seattle area

I have a friend with a pair of Red Rose Model One tube amps. Below is a link to an expired listing. Red Rose is no longer in business. I already contacted the listing party for a suggestion, with no luck, so I am asking for a referral to a tech who may be able to repair this, hopefully located in the Seattle area.
