DIY Variable AC Power Supply

DIY Variable AC Power Supply

I build a variable AC power supply, 0-30 VAC on the banana jacks on the front panel, 0-140 VAC on an outlet on the back panel. I do this using a Variac (autotransformer), some ordinary transformers, a relay, and a digital panel meter. I show the schematic on the white board, and some pictures of the build.
