I recently got a Marshall DRP-1 preamp from the 90s and would like to get the schematics for it. I found the Pot Board schematic, but can't seem to find a schematic for the board that the jacks are mounted to. I know it's a long shot, but if anyone could post this schematic I would very much appreciate it.
Here are both pages.
Amazing! Thanks g1!
A million years ago I made this board up in Diptrace, I found the circuit hard to follow until I redrew it. Here is what I drew in Diptrace, it might be easier to follow the signal path.
Wow, Tassie thank you very much! This is fantastic!

I had one of these about 20 years ago. It actually sounded pretty good, but I found myself not using it often for whatever reason. I think part of it was that it looked more "Marshall" than it sounded.
