Re: [motm] The great 300 VCO

Works great Larry!  Thanks.  Now for the question..  I pulled out my 300 
Schematic to update it and rang out the via the mod takes place on and 
found that the via connects pin 1 (square pad) of VR1 (Fine Pot) to 
-15V.  Correct?  The schematic is showing pin 1 connecting to +15V.  Am I 
reading this wrong?
