Well it works but it wasnt as easy as I thought it would be.
Putting in the bridge was the easy part. I still had to find a
place for another filter cap and a choke. The caps werent too
much of a problem. I removed the origonal one and was able
to fit 2new smaller ones in their place. Since I was going to
drawing a lot less current than the PS was designed I
figured I could use smaller caps. I still havent settled on
where to place the choke. Its just hanging out the side
for now. I will eventually try some fast recovery diodes but
since the power supply origonally use stardard recovery
diodes that is what I will use for now. The heat sink the
diodes are mounted on get fairly warm, maybe fast ones
will help this.
