Ah, good to know!

So yes, figure the backwards-wired 115V+115V:115V transformer isn't 1+1:1.04 at all. Losses involved. 1+1:1.35?

So it's probably best to use the N-68X wired as normal, with voltage doubling DC rectification. So you get half the current output. With an N-68X I should get 120*2 = 240VAC, rectified to 240*1.3(ish) = 312VDC under load. Correct?

312V*0.1A = 31.2VA, which is within the 50VA rating.

But 312V*0.2A = 62.4VA, and that's too far over the 50VA rating. Gotta bump up to the N-77U for a small stereo power amp. Oh well...
