Benchtop Power Supply Teardown (Topward 6306D 5V + Dual 30V at 6A)

This is an old power supply I got of criagslist for free with some other test equipment because it was dropped. In this teardown video I take it apart and straighten everything out and check outhow it's built. Then I do some research on the circuits and speculate on how it all works.
