I'm currently busy with the building of the YuSynth VCOs, and i've only left a few missing parts. I need to build a +/-15 V power supply too, to test the units.
I've changed the front panel design, and in the current form it only takes 100mm x 222mm (custom width, and standard MOTM height).
The parts i'm missing: tempcos, some trimmers, and a few styro capacitors. I plan to use LM394's instead of SSM2210 (which is costly), i hope the 1V/oct tracking will be good enough with these.
Todo's left: diode matching (1N4148), correcting some drilling errors to fix the headers, and a few soldering.
If everything is ok,i will build 4 more VCO's. :)
Big thanks goes to Yves Usson, to his great work, good documentation of the modular project, and the inspiration.
