Hello

I have a BC-221 whose ID plate says  BC-221E.   It is not an E variant.

>From the tubes, front panel controls, and TM11-300,  I think it's the AK
variant.

Looking at the front panel,  what is supposed to be behind the two antenna
connectors?

I tried discerning it from TM11-300.   I think it's supposed to be a 150 H
Choke (Part 24) in parallel with a 0.01 uF cap (Part 0-2).    Can anyone
confirm?

Thanks
