Philco 37-640
#28

Today I am sorting out the wiring from the tuning section. As I wrote before, I decided to use the tuning section from the 37-630 chassis since the coils on the original were in much worse shape, and the ones on the 37-630 look perfect. Now, I had marked all the wires from the original when I took it out, but I used paper labels cut from a sheet of return address label blanks, Sadly they did not seem to stick to the original wires very well, and I am having to sort through each wire from the tuning section, one by one, double checking each, looking carefully at its origin, and then tracing it on the schematic. Some, like the filament supply are pretty easy, others are much less so, especially figuring out each one which comes off one of the switch plates, then tracing it from the schematic to see exactly where it connects to the rest of the circuit. I have finally finished, now to put the tuning section in, and keep my fingers crossed that everything is traced out properly.
