As proposed, I started this thread for all to share your KGSSHV Carbon build experience and to exchange Q&A. This is a natural follow up thread to the Carbon Group Buy thread.
Here are the version of Gerber files used for the boards in the group buy:
kgsshvcarbonv5.zip (amp board)
kgsshvpssicfetdual2new.zip (GoldenReference HV power supply, all-in-one version)
kgsshvpssicfetsinglenewrightfat.zip (GoldenReference HV power supply, B+ and bias)
kgsshvpssicfetsinglenewl
@P3t4: The board and schematic archives are in a transitional period right now (read the stax mafia circuit boards thread). If you're after the solid-state Carbon, I think this post has links to the schematics of the Carbon amp and the GRHV power supply. As for boards, you can get your own made (links to recent Gerbers should be floating around here somewhere), or buy from someone who has extras. It'll help to review this entire thread, as I think it covers every tricky point of the build. Other
