I was watching A Christmas Story over the Christmas Holidays. It is kind of a tradition for me even though I have seen the movie several dozen times. Fot those of you who have not seen it, I highly recommend you take a look. Not sure how the humor would translate into other cultures.
Anyway, in one scene Ralphie, our protagonist walks up to an old full sized vacuum tube AM radio and presses a button on the tuner to select his station.
Now I am not old enough to remember these old sets but I do remember the mechanical push buttons on car radios.
My question is how did they work? I was thinking it might be based on a load on a spring but after thinking about it not sure how that would work.
So for the forum members that remember these old radios, did you ever have to repair the tuning mechanism? If so how did they work?
