Ok, finally started work on first stereo board of 976 MK2. First step mostly audiofool changes. From technical changes replaced nfb capacitor with 220uf (from 100) and input ground resistor changed for same value as nfb resistor. I also need to replace current sources ground resistors for higher power rating because PCB under them is bit brown.

Next step will be ltp translator matching.
