The Isolation I was speaking of was the transformer isolation between the AC input and the (induced) rectified output.

The term GROUND is a loosely used term that has strayed from its true meaning. Here I have been guilty of stating Ground, when I should have stated AC return leg. With the AC return leg of the control transformer connected to ground. Now you have AC return, AC ground, DC Neg. at the same potential. Unless I am wrong I think that is the "common ground" approach, That is a widely used and generally accepted method. I'm not condemning it I just prefer the "separate ground" approach.

Any harmonic distortion concerns here? utoh
