RF Choke on Philco 48-482
#2

Jim, you might try repairing the choke. If the coil is open and shows infinite resistance, there is a possibility that the coil wire is broken where it terminates to the leads. One termination may be the metal piece sticking out of the coil form.

If you have a heat gun or similar heater you can melt off the wax and examine the coil more closely and see where the wire may be broken. Try resoldering the coil wire at the termination points.

If you have no success repairing it, I would consider replacement with a choke of around 100 microhenries. This is just a rough estimate based on its physical size and construction, and its use in the circuit.
