Nice work, there is new thread: http://www.diyaudio.com/forums/solid-state/243345-current-dumping-amplifier.html

I can't wait to know how they perform!!
If I had to build those, I'd be in trouble, I couldn't see well enough and my hands couldn't handle soldering those smc. Those are nice to reduce board size, but soldering them isn't for old folks!
Some test results would be nice to see...

I am an old geezer and I used tweezers, that and a headset for the tough ones. If you use 1206/1210 it is real easy.
Melt a small bit of 0.015" solder on one pad, place, re-heat solder/place,cool and you have one pad down..Then solder the other lead/pad fast and your done.
1206/1210 are bigger than 0805 so they do not tombstone as easy. You do not even have to press down in the middle
Better to have two irons to remove, it is a cinch, way easier than PTH
Not at all, only classical middle quality solder station with 0.8mm tips and a classical pliers
An externally hosted image should be here but it was not working when we last tested it.
I dispose a little bit solder on one pad, maintain the smd part with the plier and solder first where i put solder on pad. Then i solder the other parts end. Really not a mess. Parts are 1206 type so really not the smaller.

My AX11 sounds very liquid like a SE amp but with lots of bass. The range is very wide and transparent. I took the input 10uf cap out for the reason that my tube pre had a big cap on it. I know I don't have any DC at the output. I love this mod. If anyone uses a tube pre, try this but your tube pre has to be with low inpedence and high Z out.

Good luck on fire-up!
Thanks for pcb.
Best regards.
I can wait ,this time i'm on ELIOT P3A .
Good luck on fire-up!
Thanks for pcb.
Best regards.
Up to time in didn't fire up the board. I will try this this weekend probably. The Bias will be set at around 40mA (between 8 and 9 mv across 0r22 emiter resistor) per NJW based on my latest experiences on BG1/VERSATIL.
