I am really stuck with this one.
I am 100% positive the 8DIP IC pointed with the red arrow is faulty. As I swap it from another working PSU gets the PSU going again.
The Ic has only a "177" marking. I suspected it was an op amp but it was a guess. Not sure what this little board does. I tried the common single and dual channel op amps and also a OP177 a precision single channel op amp... no success.
Anyone have any idea of what IC could this one be?
