[sdiy] AN299 VCO

[Oakley Sound]

A badly implemented version is also in the early PPG 100 modular VCO. 
The one I saw never worked because the design was flawed. The circuit 
just didn't make sense. I couldn't see how it could ever work as it was 
built.

So I changed it to be more like the Prodigy design and then it worked 
just nicely. Quite a few track cuts and additional components were 
needed though.

But then there are a lot of issues with the PPG100. The power supply 
bussing is particularly poor.
