  • Other: 1950 adjust radio push buttons

    Can anyone tell me how to adjust the push buttons on the radio in my 50 champion? I know the clear part seems to pull out and turn but nothing happens. Do these move the dial indicator? Also I found the two left do not lock in like the other five do.
    Thanks

    There are two different designs.

    The ones with an ODD number of buttons, either 5 or 7 adjust like this:
    push in the button and turn the clear tip until the needle moves to the station you want.

    The ones with a EVEN number of buttons, either 4 or 6 adjust like this.
    tune in the station manually with the manual tuning knob
    turn the button you want to set counter clockwise a turn or two
    push that button in
    let the button out and turn it clockwise until is is snug but not overly tight

    The ODD number of buttons design is very fragile, fussy, susceptible to dust and dirt, and especially susceptible to being forced. There are little keeper rings on the mechanism that get torn off when the buttons or the manual tuning knob are forced by a heavy handed user. That's why the design was changed in mid 1950 to the one with an EVEN number of buttons.

    Don't pull the clear tips out, just turn them. If the needle does not move, don't force them. The needle is screw driven in one direction and spring loaded in the other. If the needle skips, the mechanism is too dirty or rusty for the spring pressure. Turning the knob too hard when the mechanism is dirty or rusty is how they get broken.

      Thanks RadioRoy
      The radio seems to be operating, after it warms up it picks up static and what sounds like a mix of very week stations, but the dial does not move. I have an old chassis like it that is beyond repair and I was looking at it to see how to remove the bezel but so far have not been able to get it loose. From what I can see it looks like the buttons move the tuning slugs directly and should work without the dial moving. I had in mind tuning in a few of the buttons to local stations if that would work. I just got the car home and have not removed the radio. I am also going to install an aux input jack for use with an mp3 player, I have around 5 days of big band and 50s rock mp3 files on jump drives I use when traveling.

        Unless your car has been upgraded to 12 volt you may have problems with outside sources of tunes.

          Jim,

          Shoot me an email and I will explain how to take off the bezel without damaging the fine wires to the three tuning coils.

          The "obvious" way to do it is the wrong way.
