Four-Phase Systems - The Power Supply I tested, broke, then fixed.

The power supply when I got the IV/70 was anything but "ready to go". It was filthy. There was no documentation, its performance was marginal at best and finally I simply broke it because I didn't know what it was unhappy about. In this video I explain how this power supply being of a Linear design makes my life a lot easier than that of a more modern Switch Mode Power Supply, how I figured out what my problem(s) were and finally for the first time I test my repairs and see if it all works in the computer itself. (but with no boards installed, so I'll spoil that one right now) Remember to follow me on Bluesky at "@CelGen.org" to keep up to date on what I am doing and what might be happening in the next video.
