I'm working on a SB-101 and a couple of the tuning slugs in the
hetrodyne osc are frozen. Whats 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 tweek 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? inpregnated 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 mneter crystals share a long coil form with seperate 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.
