I am restoring a Philco 37-620 with a burned field coil in the speaker. The number on the coil is 32-9008. looking through a Philco parts book, the coil is rated at 65ma and the schematic shows 1140 ohms.

I wish to replace the speaker with a pm speaker and use a choke to replace the field coil.

Can anyone tell me how many henries the replacement choke should be? Could I replace it with a resistor without changing the value of the electrolytic caps?

Any help would be great.

Thanks,
