The topology of the NX-2 has been designed for a symmetrical layout keeping the on-board power supply in the centre of the chassis with the amplifying channels spaced on either side.
The NX-2 employs both Point to Point and PCB wiring techniques: High performance, immersion gold plated, 2oz weighted copper traces on custom in-house designed, double sided black mask PCB's are used to maintain accuracy to the high impedance audio signal throughout the three sensitive tube sockets, which are firmly bolted to the 4mm thick aluminium chassis to relieve any pressure on the PCB's when tubes are inserted & removed from the Gold Plated (OFC) Teflon CMC tube sockets.
On Board Edge Wise ammeters and user friendly Bias adjustment make Tube Rolling a breeze.
Integration of the NX-2 into your Home Automation system or other compatible equipment is possible with the Auto mode which has been incorporated into the 3 position power switch, enabling a standard 12v dc external trigger to automatically switch the Nixie Power amplifier On and Off when in this mode.
The NX-2 is a Japanese inspired KT88 Ultra-Linear 8 Watt Single Ended, Class A Stereo Power Amplifier
Tube lineup
Our standard Tube Line up Consists of a 12AU7 and a 12BH7A both dual triode's operating both sections in Parrallel. KT88 (Kinkless Tetrode) Power Tubes operating in Ultra-Linear mode , and an indirectly heated, High Current GZ34 Full Wave Rectifier.
Due to the customiseable nature of the NX-2 you can also choose from a range of tubes for your build. Contact us for more info.
Point to Point wiring
is favoured throughout the power supply where no compromise is made to the sensitive audio signal path by use of 6kv dielectric PTFE Turrets.
Power Supply
The Power supply on-board the NX-2 consists of superb Tokyo manufactured Hashimoto power transformer and Potted Inductor Choke. Tube Rectification and Highly regarded Fischer & Tausche Filter Capacitors.
We Believe that we have sought out the best audio transformers in production today. These are Hashimoto Transformers, out of Tokyo, Japan. They are the successor of Sansui tube technologies and are nothing but art created by skilled craftsmen of over 60 years accumulated experience in hand winding The NX-2 utilises Hashimoto transformers for it's output transformers, Power transformer and choke.
Only Japanese Kiwame and Takman's
truly supreme Carbon Film Resistors-developed specifically for audio are used throughout the amplifier.
The NX-2 boasts the use of High Resolution Auricap XO metalized polypropylene Capacitors* for coupling the three amplification stages to the 20Watt Ultra-Linear Potted Hashimoto Output transformers before impedance matching down to 8ohms and terminating at the Gold Plated CMC Binding Posts at the Rear Panel.
*Customised capacitors are also available in the custom build.
Inputs / Outputs
Two Unbalanced stereo inputs (RCA) with an Alps Blue Velvet Volume control. and a mute control from the front panel allows switching between your Turntable and streaming device convenient.
