Vacuum tube suppliers

+1 Vintage Tube Services. Great knowledge and prices.

Also very happy with Andy at Vintage Tube Services.  Been doing business with him for years.

I’ve used Brendan Bievers at TubeWorld for many years, though I got some NIB GEC driver tubes for my old Quad II amps from Tubemonger.
Brent Jesse’s web site gives me a headache. Heard good things about Andy.
I’m usually replacing ’small tubes,’ like the 12AX7 (used to roll the 6dj8 equivalents) with NOS Telefunkens, but got a matched quad of GEC KT-66s recently from Brendan; I have old stock Reflecktor D H 30s in my Veloce line stage. I’ve gotten back up sets of my phono stage tubes directly through Allnic, except for the rectifiers- which I’ve gotten from a variety of sources (currently using a GEC U52). The amp tubes, other than the 12ax7, come from Vlad Lamm.
I knew of Kevin Deal from an exotic car site I used to participate in but have not purchased anything from him.

I don't normally use tube equipment in my home, but I work on that and I purchase it to restore and sell. Mainly I choose to work on vintage tube units such as Fisher 500, Scott 299 or Mac 225. I get my tubes at thrift stores, antique malls and dumpsters. Then I test them with tube tester and than sell or use them in my units I work on.
I pay in average $1...3 per preamp or amp tubes. Recently I purchased 200 radio tubes for $20 with 6CA7, 12AX, 12AU, other 12's, 6H30, EL84...mmmm.... all at flea market. At least half of them test STRONG and ready for next unit. Seen folks there pay $20...300 per single tube so one taketh another giveth.

Check out Ron Sheldon's Cryoset site.  I have never had a bad experience with Cryoset.  Their tubes sound great and last a l o n g time!
