  • One dial (primary tuning control knob). This model was equipped either with a dynamic speaker or an electrostatic speaker (Kylectron named after its inventor Colin Kyle). The "199" rectifier tube is not used with dynamic speakers.

    Note EE: Actually it is wrong to select the electrostatic speaker for this model since it has no speaker and can run any speaker system, but since electrostatic speakers are very seldom - especially at this time - we do list it here.
