"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 .
This 10 watt design using SRPP E88cc/6922 input driver tube with all new regulated power supplies , to ensure the Teflon Coupling Capacitor is always charged, providing very low distortion, maximum gain, the driver tubes extended frequency response from 10Hz -100Khz ,excellent dynamics and absolute clarity in driving the 300B output tube.
Input signal wiring is all Neotech OCC Copper.
Constant Current Source on the 300B heaters a step up from a basic IXYS/ capacitor or AC trim pot. Hum is gone so high efficiency speakers are perfect for this Amplifier .
The Circuit is carefully optimized and retested for the lowest distortion and best bias points for linearity.
SRPP E88cc/6922 are now part of the new look Amplifiers.
>>>> This Amplifier design is available with a number of output transformer options.
