From the post
This was a request by Guilherme. It's a FET adaption of the SLO 100 preamp originally done by OldMike and modded by Brymus. I've changed the resistors going from the power rail to the drains of the various FETs to trimmers. Here's the schematic I worked from and it has a list of the voltages from Brymus' build.

This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Effects Layouts (blog). No KiCad fragment has been drawn for this circuit yet.
