Part of our new module range of space-saving designs, the Hampshire Electronics VCO in 8HP is a brand new, 100% analogue voltage controlled oscillator in the popular Eurorack format. 

The oscillator utilises the famous 3340 analogue oscillator integrated circuit popularised by a range of classic analogue synthesizers from the 1980s onwards. The 3340 has recently re-entered production, enabling a new generation of synth enthusiasts to enjoy its stability and sound quality.

The key details of the oscillator are:

  • 8HP Wide Eurorack module with thin profile (20mm deep from faceplate)
  • Aluminium faceplate in gloss black, white and gold
  • 100% analogue circuitry
  • Excellent stability and temperature compensation from the 3340 analogue oscillator IC
  • 1v per octave inputs with excellent tracking across a range of octaves
  • Coarse and fine-tuning knobs with a tuning defeat switch
  • Output frequencies of all wave shapes from less than 1Hz to over 40kHz - the module can be used as an LFO if required
  • Standard 16-pin Eurorack power connector with clear markings to ensure correct connection orientation
  • Simultaneous ramp, square, triangle and sine wave outputs
  • An exponential FM input accepting the standard +5v to -5v levels, featuring an attenuator
  • Pulse width control of the square wave output
  • Pulse width modulation input for the square wave output, accepting the standard +5v to -5v levels and featuring an attenuator
  • Classic 3340 hard sync input accepting a 0v to 5v square wave input
  • Diode protected power input
  • 23ma @ +12v
  • 24ma @ -12v


All Hampshire Electronics modules come with full and detailed instructions, power cable and screws.
