OK, I fixed the output PI-L network. Sort of. Maybe almost. The
problem was of my own doing.
In the immortal words of Homer Simpson: "D'OH!".
The bandswitch is held together by two very long screws. A stack of
fiber washers and ceramic
insulators and wafers is built up in a very specific way. I had kept
copious notes, and organized up all the bits in a box meant for
organizing SMD components. And I had forgotten the last thing - a stack
of two fiber washers and two little brass nuts. This allowed the last
wafer to short itself out against the chassis.
So I had to take apart the whole freaking thing over again. Luckily, I
still had all my pictures and copious notes, and it went much faster. I
am now officially an expert at taking apart and reassembling CX7 final
cabinets. A skill which I'm sure will serve me well in life :).
I am now seeing 115W out on 40M. No sparking or arcing. Less on all
the other bands. Broadband works.
