Light weight as switch mode power supply. Not dared to power up yet but is
there any problem concerning the power supply with runnung one power amp
only, disconnecting the rails to the other amp, either for low power or high
power audio throughput. How and what is the function of the 2x3 inch board
on the casing bottom , between outlet section and ps, that presumably is a
power or overload monitor and runs 3 wires back to the ps. It has a Motorola
TO126 labelled 715 (MJE715 ?) and 2 x 400R and little else. What do the 3
wires do ? switch off both ps sections or one at a time?
