Philco Model 66 Repair
#27

Measure the voltages on all IF transformer connections. Two should have HV on them if the resistances are correct. If you don't find any HV at the IF transformer you may have a missing or broken wire. On the IF transformer the connection that is not connected the pin2 of the 6A7 but shows 10 ohms between it and pin 2 should have 245v on it. If not connect a wire to that connection of the IF transformer and pin 3 of the 42 tube. Make this connection with the set OFF unless you like getting knock on your backside. Don't ask me how I know!!

Thankyou for the kind words sir. I double checked it with my component tester and it read 2.7 ohms at .02mH.Stormlord5500 — 08:14 AM
