2017 : New 2A3 Mini (or 45)

So here is the small or mini version to our reference 2A3i. The Mini is constructed with the very powerful and quiet 12AX7, to yield a single stage pre-amp. We'd considered using both 5687 or 6H30 tubes, but both will require a 2-stage design (plus the availability of tubes is not as good as that of the 12AX7s), which wouldn't sound as direct nor realistic. Those who listen to the these 45/2A3 Triode tubes with little output power isn't worried about gain nor drive anyway, so to tube connoisseurs, the quality and refinement are far important. Showing our prototype, the power and choke transformers will be handled by the Canadians (due to space, as well as, the availability of international voltage). Output transformers will be expressed by the very best Hashimoto, or equivalent (As shown is using the Tamura). For parts, lots of Mundorf ECAPs and Coupling caps will be used. Tube sockets for the 12AX7 and the GZ32/5V4 are made by 3Q Japan. Cardas Rhodium RCA and Gold Binding Posts will be standard. Alps Blue will be used, but those who wanted, like what's shown in the photos, it can be upgraded to DACT, and the pictured matching DACT polished stainless steel knob. For those who want to unleash its full potential with our matching pre-amps, we can turn this into a pure power amp, with a Triode Lab name plate over the volume control holes. The sample built is a 45 with an exceptional 2W before distortion, thanks to the high-end Tamura output transformers. This is why most 45 amps come in 1.5W only. Dont forget to ask about the 45 Mini RS Parallel Mono Blocks with double the power!

"Going up in price, the Triode Labs 2A3i sounded superb, with resolution and richness fully returned to the upper mid-range compared to the solid-state amplifiers. It gave back texture to violins and allowed me to hear strings and sympathetic body resonances very clearly."

Tube Use:

  • 12AX7 X 2

  • 6SN7 X 2

  • 2A3 X 2

  • 5AR4/5AR4 or GZ32/5V4 X 1

Dimension/Weight and Power:

  • Dimension: 22" Length x 12.5" Width
  • Weight: 35 lbs - 45 lbs, Plus Shipping Boxes and Materials
  • Power : 3.5W to 5W+ for Max-power.
  • Note: Depending on the model and output transformers - Some have better inductance, some have more power, some for more definition/clarity or better treble/bass extensions. It all depends on the design of each transformer; and each brand and model of output transformers are different - that's why they have different models for just one tube usually. As they have different timing, bandwidth, measures, phase shift, distortion, presentations, and insert loss - so on each model, we have to fine tune and maximize use of them, rather it is the output transformer, the choke, or the power transformer, they all offer different optimal working parameters, and we are the expert to extract their potential at its best to the last bit. On the other hand, the less ideal/precise designs will tell you its 3.5W because they see the transformers as just part of the calculation (rather they will meet their original design goals on paper or not at the end). This is what makes us better than the best out there.

"Moving on to the 2A3i, the design philosophy is typical Triode Lab. It had to be ultra quiet, dynamic and offer tight bass as three characteristics one rarely associates with single-ended triodes of low power. Over the years and after dozens of different SET amps either owned or assessed in various systems, I can point at the Audio Note Ongaku and Tron Telstar which hit all those marks. A few more came close, including Samuel Furon's own 300B integrated and the Art Audio Carissa SE but both fell short to various degrees on bass control. Without making the unrealistic claim that the Triode Labs 2A3i is the equal of an Ongaku or Telstar, I will say that within its very strict power limitations, this integrated gave me the same goose bumps as when I heard the mighty Ongaku for the first time. It thus joins a very rarefied personal peer group comprising a few select amplifiers by Gryphon, Vitus, Kondo and Tron. "
