This is a Firestone Air Chief radio, model 4-A-30. This is a very special radio to me because it was my Grandparents and lived here. I remember pushing the buttons and twisting the knobs when I was little. My parents presented it to me as a Christmas gift some years ago. It did not work then nor when I played with it so many years ago. Here is how it looks today:
The back:
Here is a schematic and the output secetion is unique to me, a push pull arrangement:
I recapped it and it looked like this before I started:
When I powered it up for the first time after repairs, I chose the pushbutton mode. Clear as a bell, manually tuned so long ago the station WSM in Nashville came through loud and clear. I could just imagine my family listening to the Grand Old Opry way back then. It brought a tear to my eye. I am proud to have this Family Heirloom with me.
I need to consult the Retrotechnologist though. After moving it it seems to not want to play well anymore. I have theory in these matters but little practical experience with these radios.
Oh, here is the view from my Grandparents house of the New River. I took it for granted as a child. Not so much anymore.
I hope everyone has a great week! Stay safe!
