Hi Pat,
The caps MAY be glued. Check for a spot of paint or glue on the edge and 
crack it off with a knife. This is highly doubtful though, as they are 
designed to be rotated for tuning. Otherwise CAREFULLY slacken the nut on 
the top of the coil cap, but ensure you put a screwdriver in the head of 
the bolt (on the other side of the circuit board) so that No pressure or 
stress is exerted on the coil former mounted to the circuit board. Once 
slack, the cap will turn freely and will need to be "snugged up" again to 
remain in its tuned position.
Good luck
Ralph,
Rodgers New Zealand.
