If you look at the QSC Audio schematic archive at:

http://www.qscaudio.com/support/tech...schematics.htm

Check out the Powerlight series, they all have SMPS, and the bigger ones hae PFC that I'm still trying to figure out. These are multirail amps, that switch the output stage from rail to rail as the voltage demand changes.

I ordered the parts to build Nuuk's buffer jast last week... Some BO's at Newark.

Anyway, are there some illustrations on your site Nuuk that have the diodes backwards? I'm only smart enough to paint by the numbers. That's what I picked up from this thread and I use your site as a bible.
