Jim, the likely problem area is around T507. It's construction is on page 44 of the manual.? There are four connection points on each side of this
transformer, and with the heavy wire used, and connection to the internal ground plane it can be difficult to make these good solder joints.?
Problems here can cause the symptoms you are seeing, the bad traces and swr protection kicking in.?
Good luck,,
