Sorry for bumping such an ancient thread, but I'm approaching this point in the construction of my G9.
If I understand the discussion correctly, the wiring from the main PCB to the control PCB's, XLR connectors, and power transformers seems fairly idiot proof. Simply make sure the 10-pin connectors between the main and control PCB's match wire-for-wire (no crossovers). The XLR in's and out's seem just as simple. Just follow the legend for those.
As far as the instrument jack, I can see where a good look at the schematic is in order, but everyone else seems to have figured it out with a minimum of bloodshed.
Have I missed anything??
Jakob, it looks to me like you've taken most of the guesswork out of this design, and I salute you for that!
I'm in the home stretch. I just have to get my tubes and my audio transformers, and she's as good as done!
P.S. I certainly don't mean to suggest that those who've had trouble are idiots. I had many of the same doubts. I tend to over-think these things and get myself into trouble. But then again, are you really paranoid if they really are out to get you??
:wink:
