Troubleshoot info:
"did the RTFM-thingy on Ken's website and connected the frequency pot to +VE / -VE and added a 150K restistor in series ... as mention on the website " found on electromusic.com
What connection would you make to the ccw position of the potentiometer in place of gnd to wire it between +/-V?
If you mean "how do you wire the frequency pot so that it gives a wider range, going lower than the frequency obtainable with the CCW end of the pot wired to earth", the answer is you wire it to -VE. If that gives you too much range, put a resistor between the CCW end and the -VE rail. 47k would be a good starting point.
