Help needed on Wadia W16 CDP

My beloved Wadia W16 CDP has died. Can any one point me to the right direction to get hold of a schematic diagram for the Digital DAC and Analogue output board please.

My unit is the later version made in 1997 I think.

Yes, I have already tried Wadia Digital. The couldn't help.

Great R2R multibit machine, I have no service manual for this one, but first off what’s it doing or not doing?
As it’s getting old and I hope it not the laser. As this Sony laser now is like rocking horse s**t to find new.

WADIA 16 4 x PCM1702-K dacs

CS8412-CP reciever

VRDS CMK-3.2 transport mech

Sony KSS-151A laser.


If it is something in the analog output stage, it looks easy to get at everything for measuring from the 4 x PCM1704 dacs (with red dot on them) back to the rca and xlr sockets.

Thanks George.

There is a short on the board that drags the 5V supply down in the digital area. At first thought there could be a shorted bypass cap on the 5V line  but have removed the lot proven wrong .
Suspect LDSP1400F ICs made by Logical in the digital volume control. Need the circuit to bypass that section.
