I have two RCA 5751s that made my CJ PV 9a really jump like nothing else. I think you're right though about nos. Some of my "os" vintage tubes measured well, but crapped out pretty quickly. I'm thinking mainly about a pair of 12ax7 bugle boys years ago in the 9a that lasted all of about two weeks. I've mainly steered clear of old tubes that are not new since then. But NOS would be a different story provided they were reasonably affordable. But the Psvane's mentioned above are worth a listen given the good sound from the 12ax7s I've used recently. Much thanks for the suggestions.

Cannot sub a 5751 for a 12AT7.

  I knew that but was really commenting on how good the RCA brand sounded when I've been able to use it. Thanks for the reply, but it's hard to get four NOS ones, but if I can find them I'll try to get them.

      I'll look tomorrow. Generally don't look on eBay for tubes but sounds like it's worth it. Know of any reliable tube sellers on eBay.

        Thanks for the info, but I just ordered five nos Sylvanias AT7s for a tryout. Will have to curtail spending for a bit. My portable dishwasher sprung a leak last night. Replacement cost best part of a grand. An unexpected pleasure. Wish I hadn't ordered the Sylvanias now, but they are on the way. I hope they are worth it.

        Sylvania tubes are very good. You will like them. Next to RCA I like Sylvania.

        Thanks for the encouragement. The dishwasher crapping out was bad, but even worse is doing dishes by hand till the new one arrives.
