[R-390] More stuck slugs

[N4TUA at aol.com]

Hello A and NONA Friends,
I finally have reached the point of doing the fixed IF alignment and guess 
what. You got it. Stuck IF transformer slugs. I have inspected them closely and 
do not look to be cracked or broken. Are there any ideas from the group on how 
to get the slugs turning again? How about the WD-40 idea? I have two that 
will not turn T501 and T502. Any and all help would be greatly appreciated.
