The support thread

The Rev J boards are probably the easiest to build and most thoroughly documented of all the DIY 1176 projects. They are based on the Gyraf G1176 and are compatible with parts lists intended for the G1176. Read more about the added features here.

Each Rev J board set includes four boards:

*One Main Board with built-in power supply

*Two Control Boards for rotary ratio and meter switches

*One Power Supply Board for powering two or more main boards from one supply (as in stereo or dual mono projects). See a completed board here.

Boards are SOLD OUT!
