Example 1950-1960 AM Tube Radio Operating Guide

DISCLAIMER: This guide does not replace manufacturers?specific instructions for tube radio operation.

WARNING: Make certain you verify the operational condition of a radio before using it. Most old radios do not meet today’s manufacturing safety standards and may pose risk if operated in an unsafe manner.

GENERAL: This guide covers AM tube radios manufactured between 1950 and 1960 that operate using an alternating current (AC) power source. It describes the basic operation of these tube radios.

• INSTALLATION: Place the radio on a dry, level surface away from stoves and heaters, and out of direct sunlight. Plug the power connector into an AC outlet.
• BASIC CONTROLS: Tube radios generally have at least two controls: ON-OFF-VOLUME and STATION TUNING.
• ON-OFF-VOLUME: This control, usually operated by a knob on the radio, turns the radio on and off, and increases and decreases the volume by rotating the knob clockwise and counter-clockwise.
• STATION TUNING: This control, usually operated by a knob on the radio, selects a radio station by rotating the knob clockwise and counter-clockwise.
• OTHER CONTROLS: Tube radios may also have additional controls such as TONE and PHONO-RADIO.
• TONE: This control, usually operated by a knob on the radio, will vary the sound from bass to treble by rotating the knob clockwise and counter clockwise.
• PHONO-RADIO: This control, usually operated by a knob on the radio, will select either phonograph or radio operation by rotating the knob clockwise and counter-clockwise.
• ANTENNA: Tube radios manufactured during this period usually have built-in antennas that may require the radio to be turned to face a direction to get the best reception.
• MAINTENANCE: Tube radios should be inspected by a competent radio service technician whenever they fail to operate correctly.
