the first thing i'd do would be to check if there're signals coming through to the mixer pots (to decide where the bugs might to be found: mixer or vco).
then you might want to follow the troubleshooting guide from ray's site (triple check wiring, values, cold solder joints, shorts, broken paths etc).

i'm worried about the fact that both vco's can't be heard...mmmh
may be similar impact but different reasons?

cheers,
matthias
