I have over 1500 vacuum tubes
Is there still a market for those??
My parents had the TV they bought in 1970 all the way up 'till '94.
Here's one of the better sounding tubes of interest to audiophiles. It's a modern tube of Chinese manufacture.
Gold plated connection pins, cryogenically treated ..... US$166.95 on sale. Some types are only ten bucks or even less, but this is the cream of the crop, until you get into some of the New- Old Stock RCAs and Telefunkens from the sixties. Double that price for NOS, Cryo'ed top brands.
