Can someone help with my 115v build.
I have proper rail voltages on -+ and can trim them properly.
On the Ground DC output of the PSU , I am measuring -17V on G?!! I'm measuring between this ground point and the chassis start point. Very odd.
For his test I did not install the opamps. Is this why I am measuring voltage on the ground point?
If I unplug the EQ modules from PSU, I measure a proper 0v on the DC output ground. Its only when 1 or more EQ modules are plugged in to PSU.
I've attached a crude drawing of my PSU wiring if it helps along with a couple pics
