This vintage Mopar car radio with speaker/amplifier is a rare find for collectors of classic DeSoto vehicles. The Model 814 was manufactured in the United States in 1951/1952 and is a testament to the quality of automotive parts and accessories produced during that time. This piece is a must-have for any car enthusiast or vintage radio collector. It’s NOT been tested, but the tuner knob does move the needle perfectly and the presets cycle correctly and speaker amp is missing some tubes. The speaker cone itself looks like it might be OK and the radio looks pretty good overall. Ty.
