I had a "cable" on the input to the duplexer, that went to the power
amp, that was a nasty chain of adaptors. I replaced that with a short
BNC-N cable made with LDF1-50

I didn't take it quite that far, but I am putting 100W into the TX
side of the cans, and getting nothing measurable out.

The inter-can cables are the same ones throughout. They both get warm
now, but I'm having a hard time believing that BOTH failed.
I'll know more when I get it down here for a post-op.
