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.
