The original first-generation AC30 used a GZ34 tube rectifier, three ECC83s (12AX7) for the Normal channel and the tremolo/vibrato oscillator/modulator circuits, one ECC81 (12AT7) phase inverter, and EL84 tubes in the power amplifier circuit. The AC15 was powered by a pair of EL84 tubes, an EF86-driven 'Normal' channel, an ECC83-driven 'Vib-Trem' channel, and rectified by an EZ81. The Vox AC30 was originally introduced in 1959 at Hank Marvin's request as the 'big brother' of the fifteen watt (15 W) AC15 model, Vox's original flagship amplifier, because the AC15 was not loud enough with the screaming fans at Cliff Richard's concerts. Characterised by its 'jangly' high-end sound it has become widely recognized by British musicians and others, such as George Harrison and John Lennon of the Beatles, Bill Wyman of the Rolling Stones, Brian May of Queen, Dave Davies of the Kinks and Hank Marvin. It was introduced in 1958 to meet the growing demand for louder amplifiers.
