Getting out of your skill set isn't dangerous unless you're wilding a soldering iron ;) These old consoles work with parallel busses...

This concern is a bit too advanced and nitpicky for a beginner. I would say if the traces pass the continuity check and a visual...

quick update: the problem is definitely on the CHA board I've swapped the NEO-273, no change swapped the LS139, no change tested the...

They beep if the resistance is lower than 100 Ohms, you still need to check the reading itself. Edit: According to the manual, yours...
