    Hi,I am trying to prevent by bushing from slipping but nothing helps.This is the knob for the final of the Heathkit SB401.Any tips?

    Is the knob itself cracked? Is the screw hole in the knob stripped?

    Is the capacitor itself in need of lubrication and hard to turn?

    The knobs seems good,The screw is good also.I lubricated everything but perhaps I could put more where the shaft rotates.
    Thanks
