Just add a chassis of your choice to complete your own 60W Dual Mono (Stereo) Amplifier based on the Fisher PA301 audio amplifier. We put together a list of compatible enclosures that should fit everything. Minimum advisable size for an enclosure is 8"W x 6"D x 4"H for EI-core and should be aluminum because it will be used to sink heat away from the amplifiers. Toroidal transformers will need a little more room.
This 60-watt dual mono (stereo) amplifier project is based on the Fisher PA301 hybrid IC amplifier. This is a unique chance to work on a modern do-it-yourself project using historical solid-state circuit architecture. The circuit diagrams and build guide are provided above in PDF (Kit Instructions and Schematic). This project offers a special link between traditional audio engineering and contemporary do-it-yourself skills. This kit valued at over $229 offers a fantastic chance to make a piece of audio history with your own hands.
Skills required:Exercise necessary safety precautions when working with power and mains voltage. Do not touch components while the unit is powered on or plugged in.
