New DIY VCO Maxx VCO-4A

[tomg]

I keep looking for the perfect DIY VCO. I may have found it.

Maxx VCO-4A

The VCO-4A is modified from the Moog Prodigy. It features saw ,pulse ,tri 
and sine waves. fm, sync, and pulse width mod. It can be build with two
TLO74s, one 3O46 and one 2N4392. The tri out is very good with only a tiny
hook at the top of the wave. The sine being derived from the tri exhibits the
same small glitch but WOW! is it nice. Sync is not yet implemented I was so
excited I had to post it right away. Future development includes Sync and a
dual version. I'll do a parts list and pc-layout in the next few days.
