Philco 37-89 Ist IF
#1

Hello, Working on a Philco 37-89. I needed to take out the 1st IF because 2 wires were falling apart. The schematic (Riders 7-29) shows only 4 wires. The black wires in the picture are the ones with bad insulation. They are not on the schematic. One wire goes to pin 5 of the 6K7 (IF) tube and the other goes to ground. There is no other wire connected to pin 5 but the schematic shows pin 5 going to ground. I ohm out the black wires and I get about .3 ohm. It looks to me like the black wires are wrapped around the core abut 2 times. Any idea what this is for? It is going to be tricky getting new wires on there. Looks like I will just splice as far in as I can. There is nothing like that on the 2nd IF.
