Re: Power supply repair

In this case the fuse was still good. I had to drill out the two
rivets to open the case so no one had tried any repairs before. The
voltages are reasonable. According to my multimeter both 12 volt are
at 11.78 and the 5s at 5.13 1nd 5.11. That's under a light load.
Maybe I should hook it up to something and put it under heavier load
for a day or two.
