KORA Mercury Schematic Diagram - LORLIN Rotary Switch replace by ELMA 04

[tiefbassuebertr]

This very fine sounded integrated amp uses only very cheap plastic rotary switch from LORLIN with very bad reliabiliy.
Replacing was necessary. I have made some images of this procedure. First pic is the schematic diagram, ceated already some time ago (unfortunately without the RC receiver unit - maybe an other member have create this for upload here) - until now not to find on the web - so I think.

Who can upload the schematics from the other amp devices of KORA audio devices ?
