You're welcome. It came from necessity as I was having trouble taking that
first step to close. I spent almost an hour tweaking my two 300s to get 8
octaves really good. After Paul spent all that time designing one that
could, I was not going to stop until I had it just right. I was very
pleasantly suprised at how easy the process actually was. Both of my sine
symmetry adjustments actually came out very close to the mid point on the
trimmer. I used the scale on the front of my o-scope glass to judge that
each half was the same width.
If the VCO is a 9 or 10 on the difficulty scale, I guess I can build any of
them.
