Hello again! I have a Philco Model 37-670. I have restuffed block caps, replaced paper caps, replaced all out of range resistors, checked the tubes, checked the volume and tone controls, checked the field coil, filter choke and output transformer. The radio will not make a sound. The input transformer has four sections. the two 30+ ohm sections are OK. The 217 ohm section measures 219 ohms. The 200 ohm section that appears to handle the plate voltage for two 6J5 "driver" tubes is not generating a reading. Does that mean it is open/bad and what may I do to rectify the situation? Many thanks for any assistance!
