09-07-06: Snook2Ha! Now the statement makes perfect sense. He told me the same thing, but specifically regarding Siemens CCa tubes. He's the best in the biz. You can take the quality of his tubes to the bank.
My info came from the gentleman who owns Vintage Tube Services. I ordered new tubes and he explained the problems he has with NOS in bulk. He checks all tubes before sending them off. Lots are failed or don't test to his standards.
However, given his strict standards for tubes, I'm not convinced all the tubes he discards are junk. It'd be fun to try his rejects.
