Official M2 schematic

Ok, I hear you. But if you have only heard the plain vanilla ACA, don't underestimate the difference the premium parts make. Maybe it's the SE sound I like, but to me it's just so special. And even better in near field on a desk. I use it in my office with FR Karlsonator speakers.
 
As a happy builder & user of M2 I have a memory of seeing a schematic for an M2 that had been modified to accept a single ended supply. I'd like to revisit it for the purposes of simplifying a small desktop mini system but my google foo is failing me. Does this ring a bell for anyone?
I've run mine on a pair of these with the outputs wired in series. Can't say much more about it other than it did work, no magic smoke. Like the above mentioned, I built the ACA for portability and enjoyed it so much I haven't gotten back around to the "portable" m2.
