Philco 40-140 Field Coil Replacement
#6

All good ideas above but mostly to address hum. If you have low volume, I would start looking at other things. Have you replaced the old caps and checked the resistor values? Also have you checked the tubes? After that is done, if the sound level is low, may be time to check the IF alignment. Also, do you have a good antenna hook up? So many things that can affect volume level and I doubt it has anything to do with your changing out of the field coil with a resistor. Check voltages on the tubes. Open antenna coil? Good luck.

One other question after thinking about it a bit. Do you have the original output transformer on the radio?
