Hi can you tell me how to adjust the Shunt Current on the Placid for Dvcc and the Hd Placid for Avcc if possible please ? Is it critical ? I have cut the traces from Vd to the Avcc.

No need to cut traces, just remove the VD pin to the AVCC module.
There is nothing too hard about readjusting the current, just aim for ~50ma being shunted on each. Start at say 250ma CCS current and adjust as needed.
Cheers!

Thank you everything works very nice. Just wonder on the HD for Avcc the transistors are about equal hot, but on the other Placid for Dvcc the QNI is almost cold and the QPI hotter than those on the HD. The Dvcc needs more current ? Edited by user Sunday, October 16, 2011 8:09:17 PM(UTC)

What is the CCS current for each?
As long as they are operating in a steady state at the target voltage with the desired shunt current then you are just fine. :)

320 ma for the Dvcc and 200 ma for the Avcc ! With about 50 ma. " headroom ". The Dexa Discret opamps works fine in the common feedback in the Legato 3.1.
Looking forward to hear it. Only have to wait for my new handmade midranges with "flower cones ".
