I've been looking for one of these as I had one in college (except this is one is gray and my old one was red.)

One locally found me for a good price. It had been seriously serviced many times before.

A quick check on a dim bulb and variac at no more than 10 volts AC showed why it stopped being used: somebody had replaced the selenium rectifiers with 1N4007s ... backwards. It came up with negative B+.

Lots of shorted caps.
