Hiii...

Just got this old power supply from a local school that was clearing their shelves of old equipment. Got several of these power supplies, an old Heath Kit Oscilloscope, and a bunch of other stuff. This power supply seems to be working normally. I get variable AC on the AC terminals (my drawing designated V1 & V2), and I get a clean variable DC on the DC terminals (my drawing designated V3 & V4).

While scoping the outputs I noticed the AC wave form is not sinusoidal. Looking at the attached schematic, can you explain why this is?


Thanks...

I didn't find the right solution from the Internet.
