Philco Model 66 Repair
#14

Well first off you need to be SURE that you wired the coil back in correctly!!! That's why I said to mark the connections so they can be replaced back onto the coil CORRECTLY. They are connected in a certain order for reason if you just hook them up in any order it probably won't work. Once that is straightened out we can measure the resistance of the windings to find any open windings.
Measure with an ohm meter from resistor #10 the side that is connect to the coil and pin 5 of the 6A7.
Measure from the coil side of resistor 10 to the 800pf the is connected the the coil, the other side of the 800pf cap a connected to pin 5 of the 6A7.
Measure the resistance of resistor #15 the 32k resistor
Measure the dc voltage from chassis to pin 5 of the 6A7.
Report back.
