Philco 71 abnormal filament voltages-low volume
#5

Thank you gentlemen for your input. I will investigate further based on your comments. 

Chas, you are right, I do have a rusty chassis I will plan to solder those grommet connections after rust cleanup to clean metal

Steve, I have included a photo of the antenna coil, and I believe you are correct about an open winding. It looks as though a wire has broken loose. It also looks like a bit of solder on the end of one wire. Maybe this was an attempt to repair it earlier.
       
Rod, I have attached a schematic with the PN 59 circled in light blue. I replaced the dogbone with a smaller resistor as it was testing about 10,500 ohms.
