The Triode Lab 2A3 parallel single-ended-triode RSR monaural amplifiers were very impressive on these acoustic era recordings, with a beautifully natural tonal balance, and noise artifacts that were rendered smoothly and were somewhat withdrawn from the music, putting the musical performances at the forefront. I've been building valve amps for my own use for 15 years and I've been through most of the usual suspects (excluding high voltage 845, 211 etc) - EL84, EL34, KT66, KT88, 300b etc. Of those I'd go for a 300b amp any day. But actually I wouldn't. I've compared the 300b a few times against the 2a3 and in all cases I preferred the 2a3.Apr 9, 2017 - PARTRIDGE ENGLAND 300B PP Tube Power Amplifier Western Electric 310A Master Hand - $60,397.48.

All of this stayed on the back burner until Kevin Carter of K&K Audio told me about building an amplifier that used a pair of PP 2A3 driver tubes instead of 5687/7044/7119's. His approach was a little different than what I was considering - he used direct coupling with center-tapped choke loading - but that it worked at all was interesting.Description. This tube is a plug & play, direct replacement for original the RCA 2A3 mono Anode tube. It is nicely designed for the same appearance too. The 2A3-S will bias exactly at the original operating point. For those who whish to operate this tube at a higher power, this is also possible. You can go up to 28Watt Single-Ended, which will ...

Audio ResearchMight as well share my thoughts on 2A3 valves: Sylvania S plate fishing-pole, great tube overall and an upgrade over stock. Lacks microdynamics and air, slightly warm and muffled. Ken-Rad smoked glass, fantastic extension, super bass punch with control, very neutral, no grain or harshness but lacks ultimate air and soundstage is intimate.Jul 17, 2008 · The M2A3s come with Sovteks as standard, which are a well-regarded 2A3 AFAIK. However, I find their performance as full-range valves to be a bit lacking in punch in the lower registers. Mids and tops are divine. IMO the 2A3 walks all over the 300B as a top-end valve.

300b/2a3 se power amp kit [tu-8900e] To be released on 2021-8-20.Directly-heated triode tubes, 300B with rich midrange and heavy bass, and 2A3 with delicate expression and gentle tone, both enjoy an enduring popularity among audiophiles. The driver input is AC coupled via C1 (or C2) into the gate of the Source Follower. The output has a buildout resistor of 330Ω into the grid of the 300B. The source follower is biased at 15mA. This should give plenty of current to drive the 3ooB effectively. Here is the design of the SF, which fits into a tiny PCB:
