DESCRIPTION Very good conserved A4300SX!All is overseen,heads cleaned and demagnetised,all working as should. 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. According to consumer guides, the SX version was twice the price of its predecessor, retailing for $US 1,400. Same money spent seven years later would buy a significantly better machine.
