Complete the Standard PPA Output board instructions, then add:

  • Three extra 3k3 strobe bias resistors R33, R34 and R35
  • Three extra 2N3904 strobe transistors Q11, Q12 and Q13
  • Three extra 300R MOSFET bias transistors R20, R21 and R22
  • Three extra IRL2703 MOSFETs Q3,Q4 and Q5.
  • Build up three additional strobes and solder to positions for Q11, Q12 and Q13 (same polarity positions as the standard three strobes): solder black striped wires to P10,11,12 and non-black striped wires to P16,17,18.
