See you at SNA audio show Melbourne -OCT 2019 -NanoAT


Featuring Finement Output Transformers, simply the best !

Exhibiting in room 1202 ,featuring Nano-AT, NP Acoustics , Contrast Audio, Wyndham Audio & Teramoto.

Hand Built in Australia ,Single Ended 2A3/6A3/PX25 or 300B with Finement Nanocrystalline Output Transformers


Welcome to the new wave of audio design at Nano Audio Technology - Nano-AT

 email -  TM pending.

We build Bespoke Single Ended Amplifiers  in Australia , both SE2A3/ 6A3 using M19, Amorphous or Teramoto  Finement Nanocrystalline output transformers. (your choice)

Nanocrystalline has no real equal out on the market at present and Amorphous is very close !
The 2A3 or 6A3 uses a Loftin White inspired design .
A 6SF5 DC coupled ( no capacitor ) input tube wired directly to the 2A3 or 6A3 output tube with a single piece of Neotech OCC copper wire .
A GZ32 rectifier with low voltage drop, soft start to prolong tube life .
This design exhibits astounding clarity and very low distortion.
Lush midrange , excellent bass and very extended high frequencies.

5mm  Alloy top and bottom plates supported between Russian Birch Plywood  ( hand rubbed shellac ) acting as a vibration proof platform.

EU made ,custom wound ,low noise Toroidal Power transformers
Simply the best !  

* * please note designs and products are upgraded /changed  from time to time. 

Parts are sourced locally and overseas, mainly Japan,USA and EU

Singe Ended SE300B / E280F or 6E5P input tube in triode mode. Using Finement - Nanocrysalline Output Transformers & Dual RCA input Integrated Option with TKD Volume Control,the SE300B is also available as a PSE 20 watt monoblock.


This 8 watt design features ( triode mode ) E280F or 6E5P ( New Option ) driver tube's with Constant Current /Cascode Source on the Anode's to ensure the Teflon Coupling  Capacitor is always charged, providing very low distortion, excellent dynamics and absolute clarity in driving the 300B output tube.

Input signal wiring is all Neotech OCC Copper point to point, all hand made and bespoke.

A GZ34 rectifier is used for very low voltage drop resulting in excellent bass and dynamics. 

Dual rail, dual choke power supplies.

All Polypropylene Power Supply Capacitors.

>>>> This Amplifier design is  available with a number of output transformer options.

M19 copper or silver PSSS secondaries, Amorphous or Finement  Nanocrystalline output transformers.

The Mono - block chassis would run North South rather than East West as with the 8 watts version, ie the narrowest part would be at the front.

Please read Technical Data tab regarding these output transformer choices and performance.

With a Tesla rating of T1.3, Nanocrystalline  is a market leader for crystal clear presentation of all music styles.

It has up to 1/5 the core loss of normal silicon steel cores, enabling very low distortion and insertion loss.

It allows you to hear deep into the mix, combined with multifilar winding techniques has no equal in this regard.

Bass is fast and solid, midrange has a vividness of character as if you were there and the highs have excellent detail where every breath and nuance is captured.

Amorphous is an excellent choice, a true audiophile product, inherently musical with an extended frequency response from bass to high end and everything in between, especially the midrange truth of timbre quality.

M19 EI core with PSSS Silver secondaries is well extended  in the bass region, able to sustain high levels of DC Flux saturation for very  stable bass response and a full and smooth midrange , where C cores are a little leaner.

High end is very detailed with the silver without being edgy or bright.

We also supply with M19 copper secondaries and OCC copper.

The Teflon Coupling Capacitors we use enable a very large sound stage with absolute clarity without being bright or edgy at all.

No other component has more influence on an amplifiers sound quality than the output transformer, it is at the heart of any tube amplifier design.

Further information on drop down tab's.

Included in all designs we have EU, custom wound low noise Toroidal Power Transformers, the same brand/type that Aries Cerat use.

Rod Coleman Constant Current Source Heater & Plate  supplies for the 300B, simply the best way to achieve quiet running & performance of the 300B , a very marked improvement on AC hum pots.

Please refer More TAB for technical details and Signature Series Pure Silver Secondaries, POA

Nano-AT will release new custom wound Nanocrysalline-Finement Output Transformers & New Push Pull range of Amplifiers in 2020


This new to be released,

 Push Pull Range, fully Class A.

6005 PP 10 watts

6CM6  PP 14 watts

EL84M 15 watts 


 EL84M PP 24 watts  

Inspiration taken from  VTL- TT25 Tiny Triode Amplifiers 1991-1993.

These will be perfect for Lowther Speaker Lovers and Horn Drivers or Full Range Speakers.

Contrast Audio Range of Speakers sold in Australia are a perfect fit for all our range.

More details to follow.


High Efficiency Speakers suitable for our Amplifiers can be found at 



Nicely Potted High end Silver or copper Secondary output transfoRmers

Partial Silver and Solid Silver Options for the Silver SE PX25 & SE300B Design.

Silver wire audio transformers have been known to make an improvement in audio reproduction for decades. Silver has a higher sensitivity to flux change (200%)  enabling it to reproduce lower level  information produced by the output stage including harmonics produced  by  musical instruments. EP Quote.

 We offer transformers using Copper ,  Partial Silver Stranded Secondary (PSSS) as well as Solid Silver.

Nano-AT use Solid Silver and Gold hook up wire in the signal path and Silver RCA inputs.

These transformers are ruler flat from 20Hz-25KHz ,quite stunning performance  in our SE PX25 and our SE300B range of Amplifiers.

8Hz-40KHz -3dB 

  Our M19 range has the new 6E5P Gold Grid input /driver tube with constant current source Plate power supplies, that produce an extremely liner response with distortion down close to 0.03% for this tube.

Both the  Constant Current Source supply on the Plate's and Heaters are required to get the desired performance from the 6E5P tube at such low distortion.

The Amplifier B+ power supply is also fully regulated to enhance this particular design. 

A true High End Audio Product !

So if Silver is your thing here we are .
