Philco 40-190 resistor
#14

The only reason I can think of for adding the diodes is that the owner did not have an 84 tube so he replaced it with the silicon diodes he had. Its a fairly common mod.

You can easily remove the diodes and just restore it to the original schematic using the 84 rectifier.

In any case, If you presently have around 180V of B+ then the power supply is working and likely is not the problem with the radio not playing.
