The Vintage Pioneer SX 750 fully revitalized receiver was a high-end receiver with the perfect complement of features and performance for someone who wants good performance while not breaking the bank. The SX-750 did just that, putting out 50 watts per channel with a total harmonic distortion of 0.1%. Produced during the heyday of silver case receivers, this particular model was launched in 1976 and produced until 1977. Its retail price was around $400.
