[sdiy] New Stereoe Panner

[Ray Wilson]

Hi Ian

As always a good question. I originally intended to just use the buffers on 
the LM13700s but I found that loading them was causing distortion. Since I 
had the bias where I wanted it I just tacked on the Op-Amp buffers. I'm sure 
that with a bit more time and effort I could have eliminated the LM13700 
buffers. I just got the circuit where it sounded right and operated near 
ground and said eureka :-)

Another thing people may notice is that you can just control the pan voltage 
if you want to. That's why I put the voltages on the schematic in case 
people want to tap in there and change something to get the functionality 
they need/want.

Cheers

Ray
