Hugh,
Thanks for the reply. I will build the offboard RL circuit between the output and the speaker posts and proceed with testing.

Oh Try keep the same Nad amp , change NPN by PNP .
some one can tell me reason using Quasi stage at output ?

@chermann,
Warning Post# 2763 by dungdochi1978 is not the modification we are talking about. Read post's #2758 - #2760 and you will see the mod we are talking about.
The mod is making a connection from the - side of C7 to the anode of the 3.3V zener. Some schematics have the connection from the - side of C7 to the cathode of the 3.3V zener.
If your schematic does not have the mod, do not be alarmed, the amp will work. If you want to try the mod and see if it makes a difference in what you hear or what you measure, if you have the right equipment, that is up to you.
Regards,
MM
