Nobelium PCB Set

This is a PCB set for building your own Nobelium preamp. This is not a beginner project, so if you’ve never built a pedal before, then this isn’t for you.

I’ve tried to make this as affordable and as easy to assemble as possible, but this is a high-voltage circuit and requires special care in assembly, testing, and use. Conspiracy to Commit Electronics is not responsible for any damage or injury caused by improper handling, assembly, or use of this circuit.

Nobelium is a low-noise, high-quality, studio-grade clean preamp and D.I. It has a nice wide frequency response to be perfect for bass or guitar, and includes a switchable HPF to cut down on unnecessary rumble.

Each PCB also includes two “12AX7-LEFT” PCBs for mounting the tube sockets and a D.I./XLR PCB for mounting the XLR jack, ground lift switch, and D.I. transformer. A pre-drilled enclosure is available for an additional cost.

You can find the build document with the BOM, schematics, and enclosure drill guide posted soon! Until then the BOM can be found here
