This CS-80 power (current) stage PCB highlights:
  • Select the power transistors of your choice.
  • Stacked to heat sink, which is electrically separated from the PCB.
  • Power transistors located in the heart of the heat sink for optimal dissipation rate.
  • Locations for 2x2 Mundorf MLGO Ø25mm, Low ESR, 105ºC power capacitors close to the power transistors.
  • Or 2x3 Ø16mm, pitch 7,5mm for low profile purposes.
  • Or 2x Ø25x50mm axial types for low cost purposes.
  • RF-interference blocking capacitors in strategic positions.
  • All resistors (MOX) are long life Vishay components or equivalent.
  • Current driven high power feedback in the centre of PCB with multiple paralleled resistors, reducing noise.
  • Speaker output and extra Mosfet/IGBT connector both left and right.
  • No Boucherot network in the output line provided nor needed resulting in way better impulse behaviour.
  • Separate power (CS)stage and driving (VS) stage voltage rails.
  • Separate tracks for Power-, speaker- and RF-ground, feedback, VS-stage and input ground.
  • Milled, gold plated beryllium copper connectors, with multiple pin connections.
  • Speaker signal for signalling/protection purposes at all connectors.
  • PCB position to mount an NTC/PTC at centre, connected to both horizontal connectors.
  • Idle current can be controlled and adjusted externally by a DC-signal coming from the centre connector.
  • Dimensions: 200x80x40mm.

This DIY kit contains most components, connectors and high quality, double sided, through hole FR4 PCB. This kit does not contain Power supply capacitors, in order to allow you a wide range of choice. We recommend 2x 5000uF/100W min.
