Triplett 2590 transistor tester - different revisions?

I'm trying to restore a Triplett 2590 transistor but the schematic I have is not exactly matching the wiring inside the unit I'm attempting to restore.

Does anybody know much about these units as far as different revisions go?
If anyone has service info, could you please PM me so I could get a copy. Perhaps someone has a different schematic from the one I have.

Even better would be if someone has pictures of the guts so I could compare.

My serial number is 8203 if that matters. My unit has a 3 wire power cord out the back but I have seen a picture in a magazine article where the power cord is a two prong coming out the front of the unit. So maybe there are different revisions.

Any insight would be helpful.
