This hopefully will interest all, techie and non-techie types,
I don't think I did this years ago, if I did . . . here it is again.
This site is interesting because it shows car radios from the past, going back to the 1930's by car model. Some radios may look messy but "its historical"!!!
The majority of radios are the carmakers made models, some are aftermarkets, that were made by Motorola and Automatic to name afew.
One thing over the years I learned about older car radios was that often if you had a low-end model car it came with a single audio output stage, whereas a higher end car in the same model came with a push-pull (two tube) audio stage. This did not happen with all models but some.
I think this continued when audio output transistor stages appeared.
I guess you could have ordered the better radio, but I doubt people were aware of this or cared at the time.
I'll always remember my Dads old 51 Buick, if the radio came on but would go off and on, on its own, based on how well your battery was charging . . . that was the OZ4 rectifier tube, which cost less than a dollar to replace.
Also, some car models had black plastic push buttons, and some had chrome covered plastic buttons, better trim on the same car but a better model, some also had a separate "push-pull" audio stage mounted alittle ways from the radio in the dashboard.
Around the mid 50's car radios went from tubes, 6 volt filaments to 12 volt filaments (around the time car batteries changed from 6 to 12V) . . . and the 12 volt tube models had 4 tubes and one or two audio output power transistors.
Also, when 12 Volt radios appeared the "vibrator" disappeared, this was a mechanical device that chopped the DC from the battery so the radio transformer could make high voltages for the tubes.
Back in the late 60's as a teen I worked on car radios, for family & friends, they were fun to work on. I had built an EICO battery eliminator that supplied 6 or 12 volts.
here is the site, choose the car model if you are curious about a specific model, have fun & enjoy,
