I'm working on a SB-101 and a couple of the tuning slugs in the
heterodyne osc are frozen. What's a good way to free them up? The 20
position is dead and I've swapped out the 20 meter crystal. I suspect
the Plate tuned osc. isn't and would like to tweak it. The 15 meter
slug turns and does a good job of insuring the osc starts or not
depending on how it's tuned.
For those of you are not familiar with this style coil, they are made
of wax? impregnated paper and are tuned with a threaded ferrite slug
with a hex shaped hole for the tuning wand. In the case of this rig 15
and 20 meter crystals share a long coil form with separate coils and
slugs.
The 20 meter slug won't turn. It's stuck to the rather fragile paper
tube all the way to one end of the form..
Thank you any and all advice.

I assume that you can not turn the slug up or down?
In order not to break the ferrite slug - I would probably use a heat gun to
WARM UP the impregnated paper form - BUT not so much as to damage it.
and then try again -- not trying to break the slug
