Bought this for the car today. May not be "correct", but correct enough for me. The car has a blank hole, but the wiring is intact. This came out of an 81 Corvette. Restored by an old timey Delco radio tech... nothing beats experience when it comes to stuff like this. I have a Nakamichi tape deck in my hoard of things, so this should be fun. Check out the Tektronix old school Oscope behind it... money. FYI I paid $300 for it. Love the red LED's.
