Re: Stumped by KS 69
where does -9V connect?  
 
At the junction of the 33K resistor and the contour pot.  
 
...input wired to the wiper of the bias pot with a jumper to the 1M resistor then to ground. Is that correct? Similar question about the volume pot...  
 
Correct.  
 
One more question - what's that hole for between the solder point for terminal 1 of the volume pot and the .1 uf capacitor?  
 
That hole seems to be redundant.  
 
Note: the 220K resistor on the layout should be 220R.
