Audion Golden Night 300B Self Cancelling Single Ended Mono Block Amplifiers


Packed with exclusive Audion tech, these mono's shine in their simplicity of sound and dimensionality. We converted our pair to PX25 tubes and cherish then even more...Mini Review by True Audiophile

This Audion amplifier is a self cancelling single ended 300B mono-block that forms part of our High End line-up of power amplifiers, It uses 300B tubes for the output. It's hand built and hard wired using solid silver 5 *9’s in all of the audio path.. The amp is auto biased. It will take almost any 300B (it comes with JJ tubes) and delivers a conservative 10 CLEAN watts into 8 ohms.  Therefore, it has the power of competitors boasting 18-20W.

OK, what in the heck is self-cancelling and why is it so important?  It utilizes two voltage gain stages to produce a high dynamic driver circuit that itself drives the self cancelling single ended output stage that operates with auto bias.. A lot of the work of self-cancellation is done within specially wound output transformers. The effect is basically phase cancelation which enables better frequency response and the 300B tube to be driven better.

Here's what Audion wrote about it a while ago.. The “Self-Canceling” topology aims at canceling out second order harmonic distortion inherent in tube amplifiers. The proprietary topology accords superior impedance matching to drive the output tubes slightly harder, yielding two additional watts from each 300B, and inducing transient and bottom-end response “very difficult to find in other amplifiers.” 

Audion Golden Night 300B self-cancelling single-ended 300B is a triode based mono-block amp uses no (zero) feedback in the design. It can also be made with PX25 (11 Watts) or 2A3 tubes (7 Watts) upon request.

Wherever possible the components are sourced from Europe and the USA avoiding inferior Chinese components.

This Audion amp is best suited for use with loudspeakers of 90db or better efficiency. The amps deliver 10 watts into 8 ohms from a 300B.

A volume control on the front and mono inputs on the rear means that a pre-amp is not necessary, but is advised. The Audion Golden Night 300B Class A power amplifier has 8 ohm outputs and mono inputs. This has both 4 and 8 ohm outputs. It can be built with 8 and 16 Ohm taps at no extra cost.

The Audion Golden Night being silver wired with a large polyprop power supply is able to retrieve great musical detail and nuances, far in excess of the Silver Night range.

Can also be ordered as a PX25 (7 watts)

Optional upgrades are interstage capacitors and superior resistors. Prices quoted per request due to changing market pricing.

Components of the Audion components:

  • Transformers and chokes are design and handmade by Audion: Mains, chokes and output transformers.
  • Superior quality parts sourced from Europe or the US. Even the capacitors are made to Audion’s exacting specifications.
  • Chassis’ are finished in-house which includes powder coating and electroplating to ensure quality.
  • Special voicing of Audion amplifiers requires every part be meticulously designed to meet their standards.
  • Every component is hand built usually point to point. Once burned in they listen again in case they are not satisfied before releasing each unit.
