Seeking 40-508 tube layout diagram
#1

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?

Schematics.

No tube layout, but that could be figured out.

The tube layout is available in our Library located at the bottom of the Home page.

Thanks for the responses! I have the wiring schematics, but the problem I'm having is someone had clearly gave up an attempt at rewiring or modifying the chassis, so it's not matching the schematics anymore. I just want to make 100% sure I'm placing the right Loctal tubes in the correct sockets, then I can fix the jumbled mess underneath from there. The Type 80 and the 42s are obvious, but the loctals are less so and I just need a sanity check.
