Sigmatron 112E Electromagnetic Field Driver – Vintage Educational Test Equipment

Sigmatron 112E. Powers on, unsure of what it is designed for, or if completely functional. I have included photos of the inside, which appears to have some power transistors and perhaps some form of switching power supply. I have not measured the output jacks or transformer output. My best guess is some sort of fixed pulse-width output with adjustable amplitude or frequency.

Sold as-is!
