Quick question. Which is better--buying a used RCA tube that tests as new or buying from Tube Center, where I know its NOS but I'm not guaranteed a brand?
EDIT: I really wanted RCA, but didn't want to pay NOS prices so I went ahead and bought a matched pair. I called the guy's shop and he said that he found them in an abandoned industry machine that was powered by hundreds of them so each wasn't passing much current. He claimed they all tested as NOS despite being used and he was able to match pairs out of most of them. He said he was getting to the end of them but had yet to receive a complaint.
He also had a 100% Ebay rating and said he'd take them back if I'm not happy. In the future I'll probably stick to Tube Center, but it seemed like a good deal (famous last words).
