9720 VCO finished and a small problem

[Mitchell Hudson]

    I just built the Paia 9720 VCO. Another very fine kit form those
guys. everything goes together well. Lots of nice features, like the LFO
switch to turn the upper VCO into an LFO. Built in glide is nice. The
range of the pitch knob feels very very limited, though you can sweep
throug any pitch with a CV.

    I just built the kit and everything worked on the first try. Though
the sound seemed a little weird. When I look at the waveforms on the
scope, they look really wavey (no pun intended!), like they have a sine
wave superimposed on them. I made a picture similar to what they look
like in photoshop

    Anyone have any idea of what might be going on here?

Thanks
