Sometimes you have to both wonder how the sets worked when they came back, and also be glad for the education that all the troubleshooting provides.
My great-uncle had a late fourties Crosley-Mohawk (CDN) table top set in his spare bedroom for guests. When I inherited it I set about getting it rebuilt and found that it wouldn't work at all. (I always troubleshoot first and recap later). All the B+ voltages were screwy and ultimately I found that a wire was just plain missing, that wire being the one that tied the B- buss to the negative side of the PS circuit. To find it I had to trace every single wire and every single part in the set to find out what was missing, and that was only after I gave up testing voltages, and scoping signals and not getting anywhere. Once I installed that tiny little bit of wire that set sprang to life as if by magic!! I lost a lot of my hair to that set .... pure frustration! I always wondered how my uncle got that set back from the shop .....
