Hi ! I'm french new DIY, discourage.. :)
I try to perform resistance check but i failed..

here is my prob >

Terminal 6, 10 > 2,9 kohms
terminal 7, 9 > 0
terminal 13 > ok
terminal 14, 20, 22 > 0 kohms
RCA ground lug > 0kohms
RCA center pin > one at 98,1 Kohms and the other 88,8 Kohms

Hello there,

You have done the shoring mod on the headphone jack, which will make your resistances at terminals 6 and 10 0 Ohms.  Are you sure that 6 and 10 aren't 0?

7 and 9 go to ground through the 3K resistors, I would suggest rechecking these.

14, 20, and 22 are supposed to be 0 Ohms.  Do you get a different reading than 0 Ohms there?  If so, what is it?

The differences at the center pins can be ignored.

Thanks a lot for your answer.

It was 6 and 10 at 0 komhs .. because of shoring mod > ok

Other resistance Ok.

I do the voltage test > ok for everything :)

I'm writting you and guess what ? I'm wearing headphone  ;)

Thanks again
