John,

My notes include this from Bob Camp <[email protected]>:

"The material in the IF slugs is different than the material in the RF
slugs so don't mix and match. "

This would imply that what you report above is right.

(The R-390 non-A is a different matter altogether.  It has slugs of both
different diameters and different materials, and may even have slugs
selected for best tracking in each transformer.)
