Please note we now source  Finemet® Output Transformers direct from the Manufacturer in Japan.


In these days of mass produced Amplifiers from a Plethora of Auction sites ,many with cheap components, we offer a High End product with Audiophile grade  Components, to fit your personnel requirements with a three year Warranty on parts and build, tubes warranty depends on manufacturer chosen.


We build hand crafted Single Ended and Push Pull Amplifiers  in Australia  SE 45/50/2A3/6C4C/300B/EL509 and Mono Block Retro 30 watt Push Pull  7591A / 7868/5B-255M  with  Lundahl HiB, M4, Laminations , Amorphous or R Core Orient Steel  Output Transformers 

 ( your choice) .


Arguably  the most important part of a tube amplifiers parts list with the greatest influence on the sound is the Output Transformer !  followed by power transformer and last of all DC smoothing chokes core material.

Our use of Japanese Ultra High End Finemet  ® Cut C  Core Output Transformers  At Tesla T1.3  exhibiting very low magnetic core loss and low distortion , high permeability helping produce excellent clarity and speed to hear deep into the original recording .


 FINEMET® have the best permeability of all, for audio output transformers used in Single Ended Amplifiers.


Recently added to our inventory of output transformers are Lundahl Cut C core HiB M4 Laminations .

These Transformers are widely used in the  professional recording industry, Shindo Laboritories and many other high end manufacturers have installed these in tube amplifiers since 1958.

One of the best transformer companies in the world today .

More to come on these !

 The  45 ,2A3  ,6C4c , 300B and now EL509  are  now part of a range of Single Ended Amplifiers with Fixed Bias offering more power
and regulated power supplies for added clarity and low noise .

Bass is very well enhanced with the regulated power supplies.
This design exhibits astounding clarity and very low distortion.
Lush midrange , excellent bass and very extended high frequencies.

New Look chassis are underway post Covid 19 with an enhanced finish 

Low Noise  Toroidal Power transformers .


Currently we are developing Australian Made Transformers with very promising results !

Quote SOUND STAGE AUSTRALIA 

"In one of my favourite rooms – I came back several  times to this oasis – Australia’s Nano Audio Technology’s debuting and  lovingly-bespoke 300B- and 6A3-based amplifiers were alternately  valve-caressing either Contrast Audio or Wyndham Audio (also Australian)  speakers. Brinkmann’s Bardot turntable !

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

Each Amplifier is Appliance tested and tagged to Australian Standards and the power supply transformers are CE certified .
