I found a guy who works only on tube gear and is mainly into pre-war stuff about a 2 mile drive from my house in Austin. He’s done two jobs for me, crazy fast turn-around, super reasonable, very fastidious. His place is like a museum of antiquarian gear. I consider that a blessing, cause I loathe shipping gear as well.
I did use Bill Thalmann (RIP)-- first class guy.
I think Ben, who used to be at the Stereo Exchange in Manhattan, had a shop in Brooklyn and was authorized for a lot of more modern tube gear but I don’t know if he is still around. Peter L. also did ARC at one time.
I think you just have to dig--@inna- you are in NY metro aren’t you?
