I ended up removing 2 IF coils and drilling out and replacing the slugs.I
used super glue to immobilize some of the coil windings and stop the forms
from turning.
Thanks for the toothpick & glue idea. I'll try that next time.




90% of the time this is caused by worn tuning tools.

I think it's about time to bring up the old "tuning wand" idea
again for the new guys. A tuning wand is a plastic rod with a
piece of ferrite on one end and a brass slug on the other. The
idea is to insert the wand into a coil and see if the output
increases or decreases. The brass end reduces the coil inductance
and the ferrite end increases same. If the circuit is tuned
correctly, inserting eaither end will cause the output to drop.
No sense trying to remove a broken slug if the circuit is tuned
Ok as it is.
