Im building my amp11 now, and I am going to try the 9 and 5 volt part. Somewhere I read about the ps1 that I need to connect the ground on that with some jumper for standalone test. Does this apply when I test it with the amp 11 (without casing and ground ground connected through that)?
How about the agnd In the documentation the schematic( example ground schematic for ps1) says agnd should be connected between the two amp11 and the ps1, but the readme file says that j5 should not be connected on the ps1 if the amp have 5 volt supply (do I need to to something special on the ps1 board then ??) .
Hope to get fast answeatrs thx in advance!!
