I own hundreds of vintage tubes. It is a game of 30 to 50 percent rejects when you take into account testing and real world performance. Just because a tube tests at 100% does not mean it will perform well. Heaters may draw to much. The tube may be extremely microphonic. A quote from Tung Sol is the best way to test a tube is in the system for which it is intended. If new tubes from EH and others are available you are best to go that route with The Tube Store, Tube Depot, or Antique Tube Supply.

Im looking to for replacement tubes for my Mastersound 845, 2 of each
Tubes in question: 6SN7 845 ECC802
I bought WE replica 845 from PSvane
now I need 6SN7 and ECC802
I saw new 6SN7 Tung-sol on eBay for about 50$ for pair. There are also vintage Tung-sol on eBay. Not sure how to proceed here. Is eBay a reliable source for tubes? I like their quick shipping and confidence in returns in case something is wrong. What other sources are reliable for aforementioned tubes?
