Finsihed two more Yusynth modules: this time two VCO's. I made the LM394 version and am getting over 6 octaves before things start to drift.

Sure. I actually used the SSM2210. I only called it the LM394 version since that's what Yves calls it on his site.

I got mine at Bridechamber. I can highly recommend them. Scott Deyo does an awesome job, and has a great inventory of DIY modular stuff. He's got almost all of the hard to find parts for the YuSynth modules: tempcos, tranny arrays, etc...and great deals on pots, jacks, and knobs.

Did you use an OPA2134/2137 too. You could expect up to 7 octaves tracking before drift. But 6 is already OK Wink
