power supply restoration
I’ve been very busy at work lately and haven’t had the time or energy to work on much, but I did pull out an ancient power supply from my pile of junk that I wanted to investigate.
The whole thing was rusty and full of years of dirt, goo, and assorted crud.
I wasn’t sure if the transformers or caps were shot, but I liked the look of it and figured it would make a cool enclosure for something else if I couldn’t get it working.
Here is how it started out.
I stripped everything out and cleaned it up as best as I could. Then I took some paint stripper and sand paper to the enclosure.
I hit it with some primer and spray paint and reassembled.
With some careful testing on a fused supply and a variac, it turned out that everything was working.
There were no shorts in the transformers or choke and the old caps seemed to be in good shape.
I will still replace them, but they worked well enough for initial testing. The only thing that didn’t work was the bulb in the jewel light. After replacing that, I had a neat old supply.
