Pioneer QX-949A in protection

Oh Sorry. 

The pin you asked me to remove from board "A" I see on the schematics comes from the Control amp . So looking at the schematics, I found other pins similar to pin 10 you asked to remove that also come from the similar circuit on the control board( 4 identical circuits one for each channel). So, On that board "A" there is a pin 17 that also comes from the control board to a section similar to where pin 10 goes. That pin measured in the mV's at the Amp board. 

So on the other amp board "B" that is mirrored board of the one that is suspect "A", I also measured pin 10 on that board and that was in the mV's as was pin 17 which both  come from the control board to a similar spot in the control board circuit. there are 4 similar circuits one for each channel on the control board.



So if all channels are similar they should behave the same I assume. So three voltages to the associated pins are in the mV's while pin 10 is 5 or 6 VDC

So pin 10 from Amp "A" goes to control pin 9

And pin 17 from amp "A" goes to control pin 8

On amp "B" 

pin 10 goes to control pin 7
pin 17 goes to control pin 10


Make sense? lol
