SKU AP-PWA01 Category


Assembled and tested module with manual.

The PWA01 is a High-End mono power amplifier based on an all transistor vintage amplifier design with up-to-date modern components like dual Toshiba TTA002 and TTC002 power transistors.


Although the specifications of this amplifier are very good, more attention has been spend to the sound of this product by listening tests and selecting the best sounding components rather than by measuring and developing to the best electrical properties.


This creates a particularly good sounding amplifier that can compete with many expensive products in the High-End market.


The module is mounted on a massive 200x150x40mm (SK47/150) Fisher heatsink for stability and is completely hand assembled and soldered to ensure the best possible quality.

Using the correct power supply, e.g. Audio products PSP01, and a large 500 to 1000VA toroidal transformer this unit is capable of driving the most difficult of speaker systems with ease.

An additional circuit board is integrated that incorporates speaker protection circuitry like DC on output, clipping and short circuit protection. It also provides signaling protection status to the power supply controller IRC01.

The module is available in two versions:

Mounted on a aluminum base plate without heatsink and the same as before but thermaly glued to a Fisher SK47/150/SA heatsink
