Philco 84 code 121 no sound
#1

Just completed replacing all of the caps and resistors. Slowly powered up with my variac and after about 30 minutes checked that all voltages were good. All tubes light up but I do not have any received sound. Just a very faint hum caused by the lights in my shop. No volume or change when moving the tuning dial. I checked the antenna coil from each terminal to ground. On one side I have 6 ohms and the other is about 55 ohms. I did not see an ohm value on the schematic but from what I have read it sounds like one side of the coil is bad. Looking for advice on where to go from here.
