I am restoring a philco chippendale radiobar that is in extreme disrepair and I need to be able to make heads of tails of the chassis. The wiring has been cut and altered and as such, I'm not sure which tubes are supposed to go where. I can't find a top-down chassis diagram of the tube layout in order to start rebuilding the chassis wiring. Does someone have one of these chassis they can refer to, or a diagram I can use?
