Seeking suggestions for 6922 tubes

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 

Mullard Mil Spec

Very hard to find but best by far.

Wrapped in paper inside the box. Checked at the factory.

Will be hoarded by some. Brent will not have them.
