Does anyone need a transformer for a linear amp supply? I have one that will deliver 50v AC at lots of amperes... It will be inexpensive if someone needs it...

However I would like to know the pin outs on the back. I can maybe fin a PS KILL signal to turn the supply off in the event of a fault in the amplifier? The Sony APS-162 PSU also works in the same series of switches although it is only 1300W. Maybe someone has some pin out info for this supply?

I cannot hear anything from the supply even at 20A load. This is on 20m to 23cms, so if I can get the voltage up to 48V or better still 50V they are worth investigating. Adding power poles to the output will be very easy.
