Question on Model 87
#1

Specifically, the subject radio here:
https://ronsradios.com/2021/07/14/philco...rs-part-1/

I have decided to use the bypass tricks discussed here to take care of the two audio interstage transformers, both of which have open primaries.

My question concerns the large three-section resistor, part (35).

Refer to the schematic here.

The resistor's sections are 3785, 157, and 640 ohms.

The 3785 ohm section is open.

A friend suggested that I scrape off the resistance wire of that section (only) and add a resistor across those terminals. However, the resistor is coated in ceramic, making that impossible.

Any suggestions? Since this is a cylindrical power resistor mounted by a screw and nut, it looks like this may be difficult to replace.

Thanks.
