DR-110 Schematic and PCB

I'm working on some DR-110's and needed a nice, clean schematic and board layout that I can pull up in eagle. I decided to redraw the two from the service manual.

I've corrected some small inconsistencies between the schematic and board. It's mostly limited to incorrect part names and swapped positions. Also, there are at least two versions of the board, both of which have test points that conflict with the schematic. I've compromised on these.

I've routed the board so that it's very similar to the original. The audio jacks have been omitted due to a lack of proper footprints, and some tweaks have been made with the potentiometers.

Images below, .sch and .pcb are available on my Github here.
