The Audio Note (UK) P4 Balanced Tonmeister Mono Power Amplifiers are Pure Class A Parallel Singled Ended valve amplifiers that use a pair of the highly regarded 300B triode valves per channel, producing a level of performance that is radically superior to the vast majority of current designs.
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
Directly Heated Triode operation
Materials and component quality
Each P4 Balanced Tonmeister amplifier is equipped with input and output transformers that are unparalleled in design, quality and performance at this price point in the field of Audio reproduction.
The balanced / XLR input transformers are hand wound by Audio Note (UK), and feature a copper primary and secondary. The core material is of the highest quality, to offer the finest possible signal path from your preamplifier.
The output transformers are similarly specified, with a copper primary and secondary. The cores are our own Double C design and are manufactured from our own SHiB material. As would be expected, they are custom designed and manufactured by us, in house in the U.K.
As is expected of an Audio Note (UK) Level 3 product, each amplifier is equipped with valve rectification, supplied by a selected 5U4GB valve.
