    ON/OFF and volume knob on the left. Tuning knob on the right. HTH.
     
  3. You'll probably need a new Cat's Whisker.

    What is the question?

    Most of the failures are capacitors, the vibrator, and maybe some
    tubes that are weak. If the speaker is the original it may be dried up
    and have to be replaced or re-built. There are places that can re-
    build the speaker.

    In theory, these are not overly complicated for an experienced tech
    who knows the older radio designs. The work is time intensive, and
    some of the parts are difficult to find, and may be expensive. But, if
    you are determined and don't mind the cost the radio can be restored.

    I used to restore antique radios and TV sets. I no longer do this type
    of work due to the lack of time.

    If you go on to the antique radio news groups, you should be able to
    get information. If you do a web search, you should be able to find
    people who can service this radio for you.

    it was AM only, no CD player, no cassett player, and no FM...

    How's that for information...

    OK, specifically what do you need?
     
  6. As long as we're all guessing, I betcha it was 6 volts.

    I'll bet that all the 'transistors' in it were large, had 8 small pins, in
    a circle plus a bigger metal pin in the center except for one that had 4
    pins in a trapizoidal pattern.

    please pardon my infinite ignorance, the set-of-things-I-do-not-know is an
    infinite set.

    Even worse was that a 1940 truck *didn't* have a radio as an option!
    (you could get an after-market one however)

    Yeah, back in those days they didn't know how to make efficient
    transistors like today! They were slow getting started, generated lots
    of heat there for, wasted power. Used excessive amount of space because
    they didn't have the chinese and mexicans of today with small fingers to
    put those vacuumed transistors together in smaller packages!
    And if you hit a bump to hard, the heater in them that generated the
    electron cloud for the majority carriers in the semi dope
    mass would fail!

    Good god miss molly!

    As far back as the 1950s, radios and heaters were optional
    equipment/accessories for cars and trucks.If the buyer of a new car or
    truck wanted the new vehicle equipped with a radio or heater or both
    items, he or she had to ask for it when he or she placed their order for
    his or hers new car or truck.My 1978 big old long tall 1978 Dodge van
    did not have a radio when I bought the van from a guy in 1989.In place
    of a radio, there was a factory cover plate fastened to the area where
    the radio goes.There was not even a hole for the antenna either.I went
    to a K-Mart store and I bought a cheap AM/FM/Cassette radio (about
    $35.00) and I bought a new antenna at the K-Mart store too.I removed the
    dashboard cover plate and I drilled a hole in the right front fender for
    the antenna.

    There was a time when windshield wipers were optional equipment for cars
    and trucks.My 1914 T Model Ford car has an optional equipment hand
    operated windshield wiper clamped on top of the windshield.Starter
    motors used to be optional equipment for cars and trucks too, so were
    wire wheels verus wood spoke wheels versus disk wheels.
