In my post, when I say, 2A3, I am NOT talking about any biplate 2A3, but specifically, the latest JJ 2A3-40s, which I suspect you have never heard, and especially - well implemented.
I just heard that tube, optimized in a amp, for three days in a row, at RMAF this weekend.

I only have 6 of the JJ 2A3-40 so I do know what they sounds like. They produce a bit more power at the higher plate voltage and killer heater current requirement most off the shelf 2A3 amps can't supply.
Soundwise, what's so special about them? I have DIY PP 45 / 2A3 / VT-52 amp as well as commercial offering from Raysonic 2A3 amp that uses PP 2A3.
In both amps, I prefer 45 over 2A3 (JJ or RCA or Sylvania). VT-52 comes close to the 45 with a bit fatter mid. Pick your poison based on your speakers but for my OB FR Line Arrays, I don't see how JJ 2A3 kicked any 45 tubes to the curb.
I also have a couple of 45 / 2A3 SET amps and I found the same result as in PP amps.
May be you need to rethink about your speaker choice.

is there a new current production version?
Hello,
That was a mistake on my part. I do NOT keep up on tube production.
I just assumed since people were selling them retail, that they were still being made. Mine are about 8 years old, and I JUST this month plugged them in !!
Can you "update me" on two questions, that come to mind ??
Q1) When did they stop producing the tube?
Q2) ANY IDEA, is there plenty of existing stock from the various tube-selling dealers?
Thanks in advance. Appreciated.

for the past 9-18 months (again not good with time) they have been slim pickens on the Internet.
I didn't buy them early on because I did not have enough clearance (they are taller than average) in my audio rack.
Dumb on my part (though I've yet to do so) as my long term plan was to place my Bottlehead tube amps on a separate shelf above the rack, as it's stupid to have tube amps "under" a CD deck and turntable with the heat generating upward.
Thought, perhaps, there was a new version, but guess not.
