After reading AFB's observations regarding the sonic differences between his 1962 and 1964 production tubes, I am very curious to discover if my 1961 tube sounds any different....
You know.... it's getting harder and harder to figure out which tube I like best! lol But what a wonderful problem to have....
Yes, this 1961 US-Amperex 6922 does sound different. As AFB noted regarding his 1962 tube, it adds just a bit more warmth and body to the mid range compared to the 1964 US-Amperex 6922, which is a bit leaner and drier. And for sure, this warmer and richer presentation, with ultra detail and a holographic 3-D stage is GREAT! Considering the 6DJ8-type tubes I have on hand, this tube is my current number one, with the 1978 Voskhod 6N23P, the 1967 OG and 1964 US-Amperex 6922 rounding out the best of the best.
But of course, this is not the last word as I have a few more little bottles of heaven coming my way... albeit ever soooo slowly.... lol
A physical feature on these US-Amperex 6822 tubes that I noticed yesterday: The sandblasted number 108. This appears to be the date of manufacture - 1961 Week 08, and it precisely correlates with the etched Philip's tube code number, *1B = 1961, February. The red-printed 61-46 is likely the date this tube was silk screened and packaged. I see comparable sandblasted numbers on my two 1964 tubes as well.
Again, what I find interesting is the similarity between the comments on Joe's tube lore and my impressions of both those tubes. The '62s, in my case, I would describe the exact same way "Joe" describes a Amp'ex US white label PQ 6922, while the '64 USN-CEP tube I would describe the same way he talks about a Amp'ex USN 6922... Go figure...
Still, I find that the expected minute difference actually makes a hell of difference during listening. While the '64 was great, realistic and detailed, I quickly felt the need to switch back to the OG, despite it being ever so slightly less detailed. There was no such pattern with the '62 tube. I've been running it since I put it on my amplifier. Color me surprised...
All in all, how would you rate the '61 US 6922 Amperex compared to the best 6SL7 offering - that Tung Sol tube? Having gotten close to the top on the 6DJ8 family (below $200 a tube at any rate), I'm curious as to what else the world has to offer (though I have 10000 hours of listening pleasure ahead of me with the '62 Amp'ex if I wish lol).
Hi Artsi,
Does your favorite tube look like this one?
"I think my 1978 Voskhod 6N23P is just a bit better. And given that you can get these Voskhods for $3 to $5 each, they are a steal. You want to look for production years 1974 through 1979."
Could you give me a link where I can buy these tubes at the prices you quote?
