Re: [help] Only noise being seen while IQ balance / phase lo / phase hi.


I think IC10 / PIN7 12V is not correct.
My thoughts:
- R38 120k is defective / faulty solder joint
- C22 is defective (poor insulation) or installed incorrectly
- IC10 is faulty (or installed incorrectly?)
The voltage at IC10 / PIN5 is somewhat low, but unlikely to be the cause of the 12V in the PINs.

that is correct, good sign
