- Page 2 The suggested panel design for the SVCO A in standard MOTM format.
- Page 3 The suggested panel design for the SVCO B in standard MOTM format.
- Page 4 Construction Guide at the project webpage or http://www.oakleysound.com/construct.pdf. This is the prototype issue 1 Oakley SVCO-A module behind a natural finish 1U wide MOTM format Schaeffer panel.
- Page 5 (34.9mm). Used in conjunction with smaller 20mm (13/16") diameter knobs this still allows for an attractive module design and finger friendly tweaking. The module accommodates either our standard Oakley/MOTM power header or a Synthesizers.com power header. Current consumption is approximately +40mA and -35mA for the SVCO-A, and +47mA and -38mA for the SVCO-B.
- Page 6 Although the Oakley Buss header is a three way connector the actual interconnect you need to use has only one wire fitted. The Oakley VCO is connected only to pin 1 of the Oakley Buss. This is the connection carrying KCV. This means you need to use only a single wire that is terminated in a 3 way housing at either end.

-15V rail. Power is routed onto the PCB by a four way 0.156” MTA156 type connector or the special five way Synthesizers.com MTA100 header. Power connections – MOTM and Oakley The PSU power socket is 0.156” MTA 4-way header. This system is compatible with MOTM. - Page 8 Calibration You should use a proper trimmer tool for the adjusting of all four multiturn trimmers. Vishay, Bourns and others make trimmer adjusters for less than a pound. Before you calibrate you should make sure that the HFT trimmer is adjusted so that the HFT circuitry is turned off.
- Page 9 261.6Hz when its KeyCV input is 5V, the tune pot set to 9 o'clock and the octave switch in its middle position. Synthesizer.com do things a little differently. Indeed, if you were to use an Oakley/MOTM build of the SVCO you would find your SVCO would operate some two octaves lower than your Dotcom VCOs set at 8'.
- Page 10 Ensure that the LO LED is lit and you have no external CV inputs patched in or via the Oakley Buss. Now turn up the frequency control to its maximum setting. Now adjust LOF until the SVCO is producing a signal of around 450Hz to 550Hz.

I hope you enjoy using the Oakley SVCO. If you have any problems with the module, an excellent source of support is the Oakley Sound Forum at Muffwiggler.com. Paul Darlow and I are on this group, as well as many other users and builders of Oakley modules.
