Re: Power supplies

Recipe for a power supply:

1 50V 25A torid coil reansformer (mouser)
1 80v 2200mfd cap
1 1500v bridge rectifer (mouser)
1 power switch (250v 30a)
1 25a slow blow fuse and holder
some wire
something to put it all in (I used an old PC tower case)
This supply will give you 68v at 25a EXACTLY after dc rectification
and the anti ripple effect of the cap. It will last for years and be
a widowmaker of a power supply.
