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.

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.
There are no stupid questions.

Wow, Tassie thank you very much!  This is fantastic!
