Did a successful repair of an old #Yamaha Digital Mixing Console #01V96 #Digitalpult: the required components for typical fader and poti damage were:
6*EC12E24404A8 small encoder,
1*PEC16-4220F-N0024 big encoder, for motor fader:
D1733 NPN: 2SCR574D3TL1;
B1181 PNP: 2SAR574D3TL1. I finally added some freewheeling diods.
