Audio Note P3 Tonmeister Power Amplifier
Audio Note P3 Tonmeister Power Amplifier
The P3 Tonmeister is a substantial stereo power amplifier in an enclosed chassis. The topology is similar to the power amplifier section of the Meishu Tonmeister and as such presents a defining shift in performance over the original non Tonmeister version.
A 5687 and ECC82 are capacitor coupled together and feed the 300B directly heated triode output valve via an interstage transformer. The result is a deceptively simple purist circuit which owes a lot to Audio Notes ability to custom wind transformers to very precise specifications.
The power supply is intentionally kept simple with a single 5U4G valve rectifier used combined with choke smoothing.
Component quality consists of copper wiring, copper foil in oil capacitors and Tantalum resistors.
The fascia mounted volume control is useful to act as a gain control when using very efficient speakers and/or a high gain pre amplifier, naturally it can also be used as a volume control when using a single source too.
