From the post
Here's a really nice optical compressor from Demeter. It offers vintage studio compression that's very transparent and a fairly simple simple build as well. The trimpot sets the gain of the compressor's preamp stage. If the signal is distorted, turn down the trimmer till it's clean. Here's the schematic for reference.
