Title: New 5F1 build...need help with PT connections
Post by: Coinroller on March 15, 2021, 12:49:34 pm

New member building 2nd amp, so please have patience as I climb the learning curve. Trying to determine where 120v Primary wires connect, using schematic below. PT connections are shown below as well. I’ve grasped the ground, CT, and HV & LV connections, but the Primary wires (Black, Brown, Blk/Wht, Brn/Wht, and Red/Wht) using this layout are confusing to me. Thanks so much in advance for your assistance! Steve

Tie the BLK and BRN wires together and connect to the power switch.

Tie the BLK/WHT and BRN/WHT wires together and connect to the white wire of the power cord.
