helphelphelp for a wadia 2000

Hi people, I've a problem by my wadia 2000 DAC. 1 channel doesn't work: so that should be not much complicate. I asked wadia: they said, the "new" company don't have schematics of the old models (!!!). So : impossible to repair! As I said: that should be easy (relatively) to repair, when I have the schematics. Somebody could help me? someone has schematics for the wadia 2000?
thanks for your help: here's my mail: fla_nic@yahoo.it
