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.
