Old VCO

This is the Front Panel of the old VCO or Voltage Controlled Oscillator. This module basically converts a voltage into a signal of varying frequency. The relationship between the voltage and the frequency is 1V for every octave over about a 8 octave range. This VCO has a very expensive IC in it which is now kaput so it will not be used again as better designs can be realized more cheaply. I suppose I will recycle the knobs...

This is what is hiding behind the front panel. It is all mounted on a small piece of vero board.
