Jvc Quadraphonic amplifier in need of some tlc the selector knob shaft is broken on one control and two other knobs are missing plus one of the four amp which are push in pull out type is faulty other Than that this is a classic and well built amplifier and if restored to its glory it would be worth quite a bit. This was the first of its kind to be introduced with OCL Amplifier protection circuit. If interested make me a reasonable offer.
