The Audio Note (UK) ANKORU/II MONO power amplifiers are Pure Class A Parallel Singled Ended valve mono amplifiers, using a pair of the highly regarded 211 triode valves per chassis, producing a level of performance that is radically superior to the vast majority of current designs.

They use a similar circuit design and topology to the legendary Audio Note (UK) GAKU-ON amplifiers. However, where the GAKU-ON power amplifiers use silver wherever possible, such as for all transformer windings, the ANKORU/II instead use copper.

They have been specifically engineered for sonic performance rather than technical specification, and fulfil all Audio Note (UK) Level 3 criteria: –

Pure Class A operation

Zero Negative Feedback

Single Ended Output Stage

Valve Rectification

Directly Heated Triode operation

Materials and component quality
