Craig,

When I was at Fair Radio looking at parts in a box, I had no idea
the potting stuff on the coils was a problem.

The guy at Fair said he stripped the wire and every thing and started over 
with new wire.

I think the, magic number of wire turns was 30 turns.
Now we do need to get one unwrapped so we can get a good number of wire turns 
to rewrap the winding on the core.

You could just cut the stuff off and count the little bits of wire.
Maybe not depending on how much adhesion the stuff has to the core.

Some times we would like to just get the end loose to make a repair.

Some day I will get the house done and unpack my stuff. I am tired of
E-mail as a hobby and want to smell some hot solder. Its more fun when I can 
look into a receiver for a reference number rather than look at a book.

I hope we can determine a solvent that will let us devolve the potting stuff.

It may remove fingers and other body parts and not be OSHA friendly, but any 
radio operator can be struck by lighting even on a clear day so some exposure
to hazards is acceptable. 

What I hate is when my diatribes get classed as spam by a mindless machine 
masquerading as intelligent.

Is my  mail that bad or what?

A rhetorical question no reply required.
