[Elecraft] [K2] unlabeled (IF?) coils?

[Don Wilhelm]

Curt,

Those are not transformers, but are shielded inductors.
I can't tell from your description, but they are either 4.7 uHy or 1 uHy 
inductors.  If the tuning slug has a flat adjustment slot all the way 
across the top of the slug, it is the 4.7 uHy, but if the slot is small, 
it is a 1 uHy.

73,
Don W3FPR
