This is the only design that will safely put the 45 tube in its best working operation point, because this is designed and engineered with the 45 tube, instead of the more powerful 2A3 tube. One set of variables/design will NOT be able to maximize the full potential of two different tubes! And this is where the 45 Mono Blocks come in, and they are very popular on 100db+ applications.
The new 45M-FFX “Supertriode”
Debut 2022
This version is similar to above, but the circuit design, the sound, is completely different. This version uses one of our favourite - the so called “super triode” preamp tube, the 6H30. Its a very linear tube with good low impedance, and powerful. For the sound - it offer that “carry-away” type sound with good tube signature like the 6SN7 / CV181. But it also combines the quietness , performance, and refinement of the newer 9 pin preamp tubes. That sound is hard not to be fall in love with. We are one of the pioneers who uses the 6H30 in the Single End Triode scheme , we started using it 30+ years ago for making triode amps. Is there a down side to it? and avoid it from making into “production” in the past? Yes - the 6H30 are generally much more expensive to the typical preamp tubes such as 12AX7/12AU7/6922…etc. And due to it’s powerful nature (easy to pickup noises from the air) - we have to spent more circuits and parts, to make it function best and operate it at the quietest condition. The grounding network for it is far more complicated than regular preamp tubes, in order to have it ran in perfection. And this why there is slight premium compare to regular 45M-FFX, with the 12AX7 driver.

Testimonial Feedback by Michael Kalellis of Arion Audio, USA
“I have heard many, many systems over the years, from cheap to 500K and up to who knows. Your 45 mono amps powering my high sensitivity OB line arrays are simply amazing. It's rare to hear this magic. Seductive, balanced, crystal clear, deep, crazy good dynamics and zero compression are words that come to mind.”
45S Mezzo
Pictured is our new 45S MEZZO (Debut 2024). For those who wants a long-form chassis , instead of running wide. This can also be fitted with a large choke and 30W sized OPT the original 2A3S chassis won’t fit/clear due to the smaller chassis footprint. The Mezzo shares the 10x20” chassis with our 211M and 2A3GT.
HASHIMOTO Transformers
2 Watts Class A
RCA Input can be located on the back, or the front side (much shorter input signal wires)
Volume Control / One-Knob (Simple Desk Policy) can be installed for direct use with high gain settings
Selector / Multiple Inputs can be an option (Alot more soldering work and wires, location of RCA inputs can also be discussed)
6SN7/CV181 preamp/driver stage will be remapped for higher gain when used as direct/integrated
Tube Rectify : 5U4 / 5V4 / 5T4 (2A Rectifier Tubes)
Standard 8 Ohms Speaker Output (Locations : BACK or TOP rear if there is space - depending the size of transformers used/selected)
4 / 16 Ohms Optional

45 RS
Single Ended Triode Stereo Amplifier
Limited edition.
Your choice of 12AX7 or 6H30 as drivers
Power output : 45 - 2W before distortion
The 12AX7 version is handmade in our usual top notch 3D classic hard-wiring ; 6H30 version required a more complicated design and required to perform best on a circuit board that is entirely grounded/shielded for the best result. We've mastered this tube over a long period of time and even though this tube required more attention and work, we just like the sound of it. Either driver-stage uses finest resistors and e-caps, and via industry best QQQ-Japan's tube socket
