Could you be more specific about "WOPL Build"?
We tend to think of a WOPL Build in three phases: 1. WOA Capacitors and Control Board (the basics), 2. New Bridge Rectifier and DC Protection Board (the insurance policy), 3. WOA Backplane Boards and all new Output Transistors (the Full WOPL).
You can do these in steps or all at once.
There is a detailed assembly instruction sheet for the Control Board.
There is a detailed assembly instruction sheet for the Backplane Boards.
There are several videos of a Full WOPL Build, search on Mark Comer, a member here.
