From the post
Here's an optical compressor I came across on FSB and hadn't seen a layout of it before. There's some question as to whether the schematic is accurate on FSB, so build with care. The original uses a rectifier array component, but I've broken that down into 4 discrete diodes (1N4148, 1N4001, etc.) since I figure more people will have those on hand than the rectifier component. Should fit nicely in a 1590B. Schematic and more info on FSB.
Schematic
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.
