    Power Output
     50W/ch into 8Ω and 100W/ch into 4Ω.

    Damping factor 70.

    Power Requirements


    20W maximum on no load.


    180W peak on 8Ω


    The Power Supplies

    A mixture of shunt for low noise and series regulator are used.

    The series regulator is only used to power the relays.

    The main pre and phono stages use a series/shunt regulator design.

    The power amps use large value bulk capacitors of 10,000µF/50V in
    conjunction with a 300VA transformer.
