Which power supply do you have? The RA-74, 84 or 94? I think the only 
difference, really, is in the the number of taps on the primary of the power 
transformer.

The FIRST choke is L1, 25H, 350 ohms in all of the above.

The SECOND choke is L2, 50H, 1150 ohms in all of the above.

In any case, neither one should be impossible to find...or to find a substitute.
