The knobs are usually designed so they cannot come off...there is a guard on the inside of the cabinet on the knob shank. The chassis of the radio connects directly to the powerline and the guards are to prevent electrical shock from coming in contact with "hot" control shafts or the chassis. The knobs can be loosened but I don't think they can be removed. During disassembly of the set the chassis must be pulled away from the knobs rather than the usual process of pulling the knobs off.
