The yusynth VCO was missing a tempco. So I ordered some from Vintage Planet and as soon as I got them (ultra fast) I put them on both the VCOs I've made and TADAAAAA! ONE OF THEM WORKED almost as expected (the other one is still too unstable). So I will hunt down and kill the wrong component. (I hope)..
(Thank god I had the oscilloscope.. the first frequency I could read was 43 KHz!!!!)
