I am wiring sony round 3. The input boards are Bulwark design. On the output stages: P & N OS 2 there are ( - I ) and ( + 1 ) connections. I do not see on the wiring diagram where they connect and my power filter does not have the connections. There are two wiring diagrams one for the orginal kit and one for the one sold at the store using the 2SK60 and 2SJ18 FET's. Any help would be great! Im using the meanwell PS. If I need a different SIT power filter i use it.
With the Output Section 2 (OS2), Nelson changed the name of D+ & D- to I+ & I- on the output PCB. If your FE PCB has D+, connect to I+ on the output PCB. Same with D- & I-.
