PAiA 2720-2A Voltage Controlled Oscillator Assembly and Users Manual with Schematics

Manual contents:

The PAiA 2720-2A Voltage Controlled Oscillator manual (Instruction Manual, User Manual, Assembly Instructions) contains details for constructing a Voltage Controlled Oscillator (VCO) to provide ramp, triangle and pulse waveforms, from a parts kit using only basic electronics assembly tools and supplies. Included in the manual are Schematics, Illustrations and Diagrams, a Parts List (List of Parts, BOM, Bill of Materials), and set-up and use (operating) instructions.

The '-2A circuitry is comprised of a front-panel and printed circuit board and uses an Op-amp Integrated Circuit, Transistors, Potentiometers, Trimpots, Resistors, and Capacitors. Control Voltages are input via pin (tip) connectors. Note this linear response VCO requires an exponentially scaled control voltage such as that from the 2720-8, 4762, 4782, and 8782/8780 keyboard controllers, or, 9308 FatMan, etc. for an equally tempered scale.
