I started the MOTM MPS build in 2018.
The panel is from Synthcube, i got the assembled pcbs from a friend.
Please use this Wiring sheet:
connect the "Noise" of J14 pin 8 to the "Noise Return Tip pin", its not shown in the above picture.
the LED pin out is maybe wrong, there are different wiring guides..
correct is Pin3 is + (the long pin from the led )
the above wiring guid is correct, my MPS is working.
a further wiring guide (not used in my build)
