[R-390] Core Values and the 390 non-A

[Tom Norris]

As I was in the middle of RF alignment I
on my "new" 390 suddenly noticed that things
weren't as linear as they had been earlier.
Chased my tail looking at the mechanical alignment,
but it was fine.

Seems the slug for Z-224, second mixer, was
broken. No binding, no undue lateral movement
in the rack, just poof. It was fine the day before.

While I know '390 cores are a pain to match,
does anyone have a red core? Just lying around....?
Or better yet the coil & the "matching" core?

Thanks in advance
