I'm sorry, the RF Choke I was thinking of is only used on the 7-J, 9-S, 12-S, and 15-S 1938 models. Those are the only chassis with an RF stage, the 7-S eliminated the RF stage for an eye tube. Anyway, for those interested and ever working on a 1938 Zenith chassis the following RF Choke is common mouse food:

Fortunately you can use a couple of inductors from Mouser to replace this:

2500uH for the large portion:

and 500uH for the small portion
