JJ 2A340
JJ 2A3-40 The much hyped, greatly anticipated new kid in my room. These ended up being a little expensive - $375CDN landed - but since the 2A3 is my happy place and they are a lot cheaper than what I was considering (Emission Labs), I'm good with this. A large, well made, heavy glass tube that again, looks like a hefty 300B..

Or as JJ puts it, "The JJ Electronic triode 2A3-40, introduced at the 2003 Las Vegas CES show, has, in contrast to the 300B triode, a heater voltage of only 2.5V. This, when combined with a heater center tap, results in a smaller potential difference with respect to the bias voltage and larger active cathode surface. The result is better sound.

"Well, Ike persuaded me to choose the JJ 2A3-40 tubes for my PB-built amp, and Eurotubes.com got them to me in two days along with a six- month warranty. I took the time to treat the tubes and sockets of my preamp and amp with DeoxIT & PresevIT; and began listening.

#1 I have an Asano 2A3 amp (I bought it new from EIFL a few months ago) that's currently running grey plate RCA 2A3 tubes from 1954. It sounds amazing hooked up to my 846A Valencias, with very little hum, but I wanted to roll the JJs as a backup to the RCAs because we regularly run the system for hours at a time to listen to radio.

The JJ 2A3-40 while maintaining the tonal characteristics of the original 2A3 far out performs it. You can read a customer review of the JJ 2A3-40 here. Leaving the SET format JJ Electronic also makes the JJ 828 which is a push pull ultra linear all tube integrated preamp and amp using eight KT88's to produce 70 watts RMS per side! This amp.

I own the JJ 2A3-40 also and in my opinion they are a superb tube. I would go with the JJ 300B and spend any money left over on the very best output transformer you can afford. I have three well respected pairs output transformers suitable for 2A3 or 300B and the output transformers make much more of a difference than the tubes.
