ok, thanks all for the input, I think I have my head around it.

I'm wrestling w/disassembly of the etek, and am thinking the problem becomes "why"?

Is a unipolar PM 3 phase hall effect controller with custom center tapped etek worth the effort over a used brushed etek? Doesn't seem likely.

Probably best to just sort out the high side. A hand full of 3 watt transformers and various regulators and some optos is a little bulky, but working is better than not, and it can have a negative gate shutoff.
