[SCHEMATIC REQUEST] MXR M-129 Pitch Transposer rack unit

[beatnik]

I am desperately trying to find schematics to repair my MXR M-129 pitch shifter .

I have tried google and all the search engines I had with no luck .

It is impossible to debug the unit without schematic, it is a very complex circuit and the ics all sanded !

MXR changed completely and I have asked to the people that currently runs it and they haven't inherited any of the old documentation

Maybe somebody here has a copy ?
