Mr. Carlson Makes a Thermatron Power Supply for a BC-348

When I was 14, I had to make a power supply for a Heath HW-32A. Mine ended up working, but it was nowhere near as nice as Mr. Carlson's BC-348 supply (shown in the video above). I didn't have a sand blaster, nor a drill press, nor much of anything else, really.
But hey, don't real boatanchor hams use Greenlee chassis punches? What's with the drill press and the hole saws?
Note that Mr. C takes care to make sure that the rectifier tube is in the proper angle FOR OPTIMAL VIEWING. That's some serious attention to detail OM. And whoa, DELICATE SURFACE MASKING TAPE from 3M? Respect! Also, era-specific looming material.
His point about the importance of the cardboard washers in the power transformer was really useful. I hadn't thought about that.
Here are the two previous BC-348 videos:
Thanks Paul!
