via a_guy_called_tom on this electro-music.com thread."Today, thanks to the terrible weather, i was finally able to complete my new TH VCO-1 oscillator stack and i thought i'd share some pics here.
I choose the VCO-1 design because its a triangle core and apparently good for FM. The few tests i did so far are very promising, i like this VCO. I didn't use a tempco and did not match the transistors for the expo converter, i have yet to find out how good the tracking is.. Anyway, thanks to TH for making these designs available for the DIY community!"
