If you got a PCB with serial XXXXXXXX-YYY-220117, you could change the following things to catch up with the latest PCB version:

  • Replace R51 (33k) with a wire
  • Replace R14 and R64 (18k) each with 20k
  • Replace C26 (10u) with 1u
  • Add R15 (10k) to pin 1+2 of RV6

Trigger Inputs/Outputs are interchanged:

  • Trigger inputs (J2 and J7) are on the wrong side. This can be fixed by cutting the respective traces and adding a wire from the J2(T) to the right end of R36 and from J7(T) to the left end of R2
  • CH/OH Outputs (J4 and J8) are also on the wrong side. Cross-wire R32 to J8 and R55 to J4 to fix it.
