Favorite nos tube?

South: I plan on ordering a new production Tesla 6922 that has had mixed reviews at AA. How a tube sounds does depend on the amps design (including the other tubes) and the system itself, not to mention indiviudal taste. I would guess however that there are some "universal" duds out there. I also lucked out on Ebay the other day and picked up a 6922 branded as GE that is either a Siemens or a Telefunken. Can't wait to give it a try. I am fortunate in that the Audion only requires one 6922 as singles are easier to pick up. You may want to search the Audio Asylum forums and see if you can find any feedback on tube rolling in your Anthem.

Yes Dekay you are lucky to have only one 6922 to deal with. I also am bidding on some Telsa EL34's for my Anthem amp through ebay. Also got lucky with a 12ax7 from Sveltana that I am waiting for that will go in the amp.

Dekay; are you comparing Sovtek 6922 pre-amp tubes to 300B amp tubes? I have an SF Line 2 pre-amp, and I like the stock 6922 Sovteks-- very neutral and detailed; some say sterile and boring. But just yesterday I put in a set of Valvo 6DJ8's (at twice the price of Sovteks) and am already noticing a slightly more "tubey" sound, which in this case could be good. The Valvos are smoother, warmer, more detailed, and a bit more prominent in mids and low treble in this pre-amp. These changes are subtle, but I'm starting to think pretty worthwhile-- too soon to tell for sure. FWIW, in their new Special Edition pre-amps, SF is using the Valvos. Cheers. Craig

RCprince, its Teles for the Jadis front end, exactly for the reasons you propose. Would love to try the Bugle Boys but have not found a source for them so far.

Craig: I recently picked up an Audion 300B stereo amp that uses (one) 6922 and (one) 5687 as well as a pair of 300B's. I have three sets of output tubes so far (stock Chinese mystery tubes, Svetlana's and JJ/Tesla's) and find that I prefer a different 6922 with each set of 300B tubes. The sharper sounding Sovtek or better yet the old production Soviet 6H23EB with the softer Svetlana 300B's and the old fuller/softer sounding Amperex PQ and standard/USA white label 6922 with the more strident JJ and Chinese 300B's. So, I am comparing the sound of these combinations of tubes. It's kind of funny in that I never rolled tubes in my hifi amps in the 70's and 80's but I did roll them in my Fender Guitar amps in order to get the sound that I was looking for. It's a lot more difficult to chose now that I am not basing my opinion solely on the sound of a Strat or Telecaster. LOL. I am also trying out different 5687's with black plate designs. Sylvania Gold murders the mystery National 5687 that came with the amp (which sounded very murky) and I have a Tung Sol black plate 5687 on the way. The Tung Sols are readily available but I see people paying very high prices on Ebay for them. Go figure. There are a couple of people that I met on the web that also have the Audion Silver Night and we will be pooling info as each of us try out different combinations. I have also found that it helps to clean the pins on the tubes with alcohal and if needed a brush.
