This is the bare printed circuit board for the VCO153 CS VCO for do-it-yourself enthusiasts. It is the exact same circuit as used in the VCO153 5U module but made for through-hole parts. A couple of choices are offered onboard and at the discretion of the builder for fitting a log-conformal matched pair and temperature compensation resistor. The board also provides power connector placements for MTA-156 (MOTM) and MTA-100 (synthesizers.com) cabling. The VCO153TH1K version comes with a 1K 3300ppm surface-mount temperature compensating resistor pre-installed.
