Nice to have it (almost) working again!

Based on the presence of mustard-colour polyester caps, my guess is now late 1950's to early 1960's. I'm not sure why the model number is of the "4 digits only" variation, which in my mind would have put the date a bit earlier. There must be some kind of reasonable explanation for that. Maybe the older numbering scheme was used a bit longer for some types of equipment.

Before, I stated that model numbers of similair equipment would start with GM, but that's for measuring equipment. Power supplies may start their model numbers with PE.
