Got this one the other day, pretty cool use of a rangemaster. Schematic is verified, but I could use some help making a digital version to upload here. Here's some pics and schematic, more on my flickr

In the schematic the cap to ground on the input is a 220p, the big one on the depth control is a 1000uf 16v, and the vactrol is labeled vtl5c4/2. Next up will be a Skreddy Pig Mine once I sort out the values from some pics a friend sent me.
