Never seen it configured as such in the threads. The easiest way would be to predict behavior on virtual ground PSU with simulation software. See about DC offset etc.
Ok soooo…Balanced unit (2 mesmerize boards) which I already acquired. Looking for a little advice on BOM first big one is capacitors. Enlarging reservoir capacitors to between 40KuF (x4-10KuF) to 132KuF possibly off board? I will start there! Oh I have also procured an octet of “super matched” 2sk170(BL) 10.0mV.
2 x 0.0047 MuF will probably be enough unless you will be hotrodding it. Load current in original form is quite low AFAIK.

Yes I plan on running at 200mV tuning.That would be standard reservoir obviously that would be (x4) not 2.
Is the signal ground referenced to chassis though? This can help with hum in some cases.
"The ground loop breaker is a 10Ω 5W resistor in parallel with a 0.1µF capacitor rated at least 250VAC"

Not my drawing, but I believe it means using the left channel designation on each stereo board for negative phase and the right channel designation for positive phase. Resulting to one balanced channel per stereo board.
Ok for some reason maybe I am mistaken I was thinking one board was NEGATIVE bias L/R and the opposite board was POSITIVE bias L/R?
You are right to get initially perplexed by the way its written on that diagram
I have way too many ideas! Has anyone amputated the Psu on a Mez? I have looked and found some stuff on VSSC but it doesn’t quite translate well to me and I believe it was a hypnotize as well (late night reading). Curious because I was thinking of integrating UBiB and MEZ for line with DCG-3 and UBiB in a separate enclosure. So integrated DCG-3/Mezmerize in 1 enclosure and separate UBiB power supply in a separate enclosure. As far as the diagram the only reason I even gave it thought was because of who posted it! New DMM showed up today SANWA PC7000! OOOHHHYEAAH!
And scratch the diarrhea of the brain!!! I would love to but way to complicated I would have to lower the output of the psu on change over. Maybe later or eventually design something from the ground up with a gain cell (Gilbert cell). Sorry guys no more hypothetical stuff. But my big hang ups are
Reservoir caps and torridals and has anyone run a D.A.C.T. Volume pot?
