Most reputable independent tube equipment repair facilities in the US ?

Holt Hilt Audio in MA ? Again, sounds familiar.

I trust only Willy Hermann with it, and he is over there.

Willy’s the best for Naks. He restored my BX-300 a few years back. Lucky for me lives nearby.

@inna , you could give Mike Garry a call at Hudson Valley HiFi in Cornwall, NY, which is not terribly far from you, just above West Point. He accepts shipments if you don’t want to make the drive. His shop is does warranty work for Luxman, as well as offering repairs and restoration on other brands. Did some excellent work on my MQ-300 after a blown rectifier took out a few resistors. Good guy.

wrm57,

Thank you. I'll keep him in mind.

West Point is not too far from me, right.
