as of ). By then, groups were preferring to use a Hammond organ and Leslie speaker instead of a Vox. Most of the remaining assets were sold at a liquidation sale in 1971. There are no definitive figures for how many Vox Continentals were manufactured. However, estimates based on serial numbers indicate 9,100 single-manual organs were manufactured. Around 4,100 of these come from the UK, followed by 4,000 from Italy and 1,000 in the US. The Vox name was later sold to Rose Morris, who in turn sold it to Korg in 1992. Since then new products carrying the trademark Vox have been primarily for the guitar player, and the Korg trademark appears on most keyboards. In September 2017, Korg released a workstation-style keyboard named in honour of the Vox Continental and highlighting the particular Continental organ sound, competing with contemporary keyboards such as the Nord Electro. The original Vox Continental is still used by collectors of vintage instruments. Maintenance The Vox Continental used relatively unstable germanium transistors in its oscillators, which can occasionally drift in pitch and required to be re-tuned. The wooden keys on earlier models are more durable than later plastic ones. The organ is connected to the mains via a round three pin Bulgin connector, which was standard for the time but is no longer in general use because it does not meet modern safety standards. Some technicians have retrofitted the power supply on a Continental to take a standard IEC 60320 C14 "kettle plug" lead. The later US and Italian Continentals have a hinged lid, which allows servicing without having to dismantle the instrument. Because the Continental was designed to be played in concert and used in touring, there are relatively few of them in good condition unless they have been repaired. Several surviving models are missing the original case carrying the stand and volume pedal. Clones Several modern keyboards feature emulation of the Vox Continental, including the Nord Stage and Nord C Series, and the Hammond SK series. There are also some software emulations of the instrument, including the Arturia Vox Continental V, a Virtual Studio Technology plugin that uses modelling to accurately recreate the electronics of the original. Notable users The instrument was commonly heard in 1960s rock music, and played by the Beatles' John Lennon, the Dave Clark Five's Mike Smith and the Animals' Alan Price.
