78-87 GM Delco AM FM Stereo Radio ETR Cassette Chevy C/K Truck Blazer in good working order. Also has had the addition of an internal auto switching Bluetooth board. You get the best of both worlds; an authentic factory original radio with modern listening options. Cassette tape path including capstan/pinch rollers and head cleaned of oxides and appropriate components demagnetized. Tape speed checked with 440 Hz calibration tape against frequency meter. Controls all cleaned with de-oxit. AM and FM sides both strong and all 4 speaker channels functioning well. The bezel is in good condition. Will fit many GM models of this era. Please check fitment.
