Hi all.

I had checked his page and I redraw his circuits like this.

I tried type B on breadboard. But it dose not work well.  If frquency 
is hi enough then it's OK. but it go down then time of up to top and 
down to low takes long time. And if you use it VCO modulation then you 
can't find the deffelence of both.
It's just a experiments, but it's so fun!
