Guess what? Some were made with the center posts of the first four tubes connected to the chassis, not to B-. I am working on one, and bought a parts radio yesterday, and both were made with those center posts connected to the chassis (original wiring). Both of the chassis I have were identical, and have otehr variations from the Rider's schematic. The schematic on Rider's is apparently just one version of the radio.
