schmatic 4 digi box

Does anyone have them or know where to get them from..

looking for schematics for a Grundig digi box GDS 310/2

I have full schematics for a Amstard box if that helps ? There are engineers books for all the boxes I think, the one I have has everything from PCB layouts to fault finding tips etc.

r these books available in shops

do you know where I can get a copy of these..

pm me

My Grundig has lost all sound on the Av, Rf and phono but i can still get the pictures..
someone offerd to fix it for me providing I got the schematics.

thanks 4 the reply
