Antique Radio Isolated Power Supply

A couple years ago when I got in to this hobby, I wanted to free up some bench space taken up by my Dim bulb Tester, a volt meter, variac, and other devices.

I wanted them to fit in a single cabinet. This is the first drawing I did in Autocad 2002. I began collecting the needed parts for it.
The problem was that I could not find a decent cabinet that did not look cheesy or homemade. About a year ago I bought a B&K 1076 TV Analyst from a Goodwill for about $8. I do not ever intend to work on vintage TV's as they take up too much room. So I parted it out. I kept the case but it was only about 6 months ago that I decided to use that for the case. So I redesigned the device to fit in the new case. This was the final design.
Here are most of the parts needed to assemble the device.
 The hardest part was obtaining the front panel. Initially I was going to use a side panel from an old computer case, but could not cut the piece I needed out of it and still have it look good. So I called a local sheet metal shop and bought a piece of aluminum cut to the size I needed. I printed the layout on paper at 1:1 scale, then punched the centers of all the holes. I drilled the holes out, or in the case of the larger ones, I used a nibbler and dremel tool.
 I painted the piece gloss black.
 This is the case to the B&K 1076

 It took about 3 days to do the actual assembly, and this is the final result.
Some pictures of the inside wiring.


Here is a short video of it's operation.
