Seeking suggestions for 6922 tubes

      btw: Whatever level of Bass resides in your media (down to the Stygian); the early Siemens iterations will convey it, unhindered and not editorialized, in all it’s power/glory.

I’m using Amperex 6922’s with the gold pins from the early sixties in my preamp and am very happy with the sound. The only other advice I can give is don’t buy the cheapest EH tubes. They came with the unit when I bought it and were full and boring sounding.

All the best.

You may like Nationals made in India with Mullard tooling, I believe.  

I collected a lot of 6922’s in the late ’90’s. The best were all specially selected by HP (Hewlett-Packard) for use in their test equipment, the stuff which put men on the moon. Tales from that era were of co-op students testing boxes of 144 factory fresh tubes, passing 2 or 3, and tossing the rest in a dumpster.

That might be why they were so expensive, even back in the day.

IME, the best of the best were H/P selected Telefunken tubes - I think I bought the last sleeve of 5 (with BOTH H/P and Telefunken seals) for $500. 1962 vintage, IIRC. They sounded absolutely silent and absolutely grainless. A testament to the best tubes ever made.

Russian  reflectors I have found work well in my canary  ca 160 amps. Also I really like them in my sonic frontier  dac3. Gold lion new production are the best of the new made tubes but I prefer  the nose tubes. I had a pair of valvo  6922 that I found wonderful they had tube beauty  and top to bottom  balance.  The gold pin amperex  are all right fi d them a bit rolled off in the highs. Something  I found the other day that I would like to try is some adapters and some new old stock western electric  tubes that were the same as 6922 but a different  pin out. They were  made for the usn.  Lol I have not come to the point where I want to let the moths  out of my wallet  to buy a matched quad. Regards
