Hello!
Can anyone help with repair TC electronic NDR - 1. The fault is in the power circuit of the pedal, there is no voltage -12 for power operational amplifiers. Does anyone have a schematic diagram or has anyone experienced something similar? This voltage is generated using the IC CS51411.

Should be something like the examples in datasheets
The CS51411 and CS51413 are functionally pin−compatible with the LT1375.
