Tuning Instability: 1936 Philco 60B Cathedral
#2

A few things in general that you should check:

Ensure that there is no oxide on the plates of the variable cap (capacitor) by fully meshing it and running a feeler gauge between the plates.

Ensure that the bearings for the rotor are fully cleaned and lightly oiled. Ensure that any grease in the bearings has not hardened.

There should be a spring clip between the cap frame and the rotor shaft. Ensure that this connection is clean and there is sufficient tension between the spring and shaft.

Ensure that the mounting screws do not protrude sufficiently deep through the cap frame to short out the stator.

Ensure that the frame of the cap is securely grounded to the chassis, preferably by braided wire.

Hope this helps.
