The A 4300 SX was an improved version of the 1973 A 4300. The main improvements, apart from a cosmetic make-over were the implementation of low-noise electronics, resulting in an improved signal to -noise ratio and frequency response figures. Needless to say, the SX version was twice the price of its predecessor, retailing for $US 1,400.00.
