This is our take on the G9 preamp.
Original G9 was designed by Gyraf Audio at https://www.gyraf.dk/gy_pd/g9/g9pd.htm
The case option will provide you with:
1) Metal enclosure, powderpainted and screenprinted. All the holes laser cut.
2) Preamp PCBs x2
3) Front panel switch PCBs x2
4) Power Supply PCB x1
Original Gyraf G9 preamp PCB can be fitted inside the case also, holes are pre-cut.
Assembly instructions, notes and BOM can be found on our G9 preamp product page.
