I recently purchased a zpa 05 ebay realized after recieving the amp has been modified to bypass floating ground switch it looks like they set it for rca input instead of balanced input. Any info appreciated. They removed switch and placed 2 jumpers close to where the number eight is on circuit board

i think phoenix gold did this on the v2 zpa when they upgraded them.

removing the switch by two jumpers was the last revision, i think.....
more important is, don't power the amp up with the original ps caps.....
