  • The thermistor usually controls the voltage of the base of the

    output transistors if ambient temp goes up the voltage goes

    down preventing sound distortion , not all radios had this

    type of circuit (excellent radio)

  • I filled in the gap with those little metal spacers from Radio Shack. Worked great. Thanks!!

  • great small little gem you have ,I love and collect almost any radio I can get for little money, seems like one 3volt photo battery may fit in there i think is cr 123 or some like that, thank you for sharing. Ernest.

  • YES!!!!

    I searched for the largest batteries of the right voltage that would fit in the radio. Then I made a metal spacer to fill in the gap. It was pretty cool having a small radio playing, but with substantial sound.
