power supply

The power supply is besides the computer the most expensive part in the system
It plays a big role in the quality of the amplifier (which is often neglected)
for my amplifier I need a solid 70V (or 2x35V) power supply which can deliver a peak current of at least 8A.
A coil transformer of 2x24 V and at least 150 VA will do best.
2 elco's of 20.000uF and a diode bridge of 25A are the only extra components. So again, only few components are needed

Simple schematic:

please pay attention to safety (not because of the rules but for yourself)
I sealed mine in a wooden box, (don't know if I'm breaking fire hazard rules)
