Tube Depot's "NOS vacuum tube sale"

Tube Depot does distinguish between "lightly used" and NOS.  Where do all the new old stock tubes keep coming from?  It's like there is an infinite supply?


There isn’t an infinite supply.   I got several rectifiers from them.  All 6 looked like they were pulls.  Absolutely no doubt they were at one time in service.  All looked poor   Several had a band of oxidation around the pins where the tube sockets made contact.  

I would never buy NOS again from them.   They did refund me but it was a bad experience.   

@oddiofyl That’s good information. I’m looking around for various nos tubes at the moment and keep running into their website via google search. 

Andy (Vintage Tube Service) is the best I have experienced within the US, but he has some limitations. He’s pretty old school too, which is fun but don’t expect instant gratification. I’m surprised Tube Depot would sell pulls as NIB/NOS- I don’t question your experience, that’s disappointing. What I got from them was pristine, but at the price-- for what I regarded as a common tube that I used to buy for 10 bucks--I’d expect the real deal. Being a "tube" audiophile is getting more difficult.

I’m actually considering a small solid state amp- possibly a Valvet- to substitute for my Lamm ML2s when I’m listening less critically. It’s supposed to be a good amp. Hard to find 12 watt solid state amps these days made to a quality level.

@whart  , I did buy some tubes (12au7s, 6922s, 6550s) from Andy back before 9/11 and I was mostly happy.  As far as Tube Depot goes, I do note that some of the vintage tubes they have on sale are specifically listed as having light use on them.  There are some Tung Sol (not the Russian reissue) EL34s that come to mind, and I think there may have been some 6SN7s listed the same way.  Probably more, but those were the only two tu8be types I was really looking at.
