Something for testing GE type M contactors?

The most over complicated variable voltage power supply I have ever seen.

It looks like PCC technology.

Looks a lot like my own MG set for EMD locomotives.

I was going to say that is may be a cab signal tester but I don’t see any labels for Hz.

It is a tester of various voltages and currents that Bob used to test the contactors for the Class B.

Bob is still putting things together with vacuum tubes?!? He must have an amazing collection of parts. I got rid of all my tube-era radio stuff about 50 years ago.
