What a fantastic resource, thank you! I think I may have found a small mistake though. On page 1, the Audio +8V Regulator section. The negative side of C108 goes to pin 6 of UA10, not pin 7 (I'm pretty sure).
Thanks :) Pins 2,3,6 and 7 are all connected on the SOIC-8 78L08 however you are correct that the trace on the PCB goes to pin 6, but if you desolder the regulator you will find there are traces underneath connecting all 4 pins on the regulator. What I might do is change that symbol with one that shows all the pins as I never really liked the fact that symbol doesn't show pins 2, 3 and 6 even though they aren't NC pins
