Thank you for the replies. I still want to get a bench power supply, but I'm now not real keen on putting power to my radio. I have other bits and bobs that need some juice to test. 6V wiper motors, switches, etc. I live in an area near Portland, OR where I'm confident I should be able to find someone that I can deliver my radio to have it worked on. I'd rather not ship it somewhere if I don't have to. I am okay with general electrical, but honestly I believe these radios transcend electrical into electronics, and while that may or may not be accurate... I feel it's beyond my abilities at this point and I would hate to let the smoke out of any old radio, much less an NOS 986771. There just aren't that many left to mess up!
