VCO Finished!

Here are some photos of the finished VCO module. You can see how the PCBs stack and the edge connectors.

It isn't fully calibrated yet. I'm still tweaking some of the billion trimmers to see how they interact. I'm finding the Sync Bias propagates through to the sine wave shape as well. I think there will be more iterations in the calibration than I thought there would be.

You can see the -10 volt regulator as I chose to run on the "vintage" +12 / -10 volts just because I can Smile

Congrats on the VCO! If you do figure out the calibration process, make sure you document it! Smile

Lookin' good! Will be nice to hear some audio from it whenever you've got it calibrated.
