If it's hitting 300 deg F..... I would say you are using the wrong

Steve,
I wonder if something other than the N-connector was the source of the
heat? Perhaps something inside the device with the hot N connector (I
think you said it was a combiner) was getting really hot and conducting
that heat through the connection to the type-N female pin which in turn
conducted it to the male connector. That would explain why that same
N-connector was NOT getting hot on the old tube transmitter. The one in
the SSPA was acting like a heat sink for something very hot inside the
combiner.

We were; but we were stuck at the time, conveyed the problem to the
customer, who then poohed-poohed our concerns, claiming that their
existing tube transmitters generating over a kilowatt through the SAME
type of connectors were doing just fine 8-/
Did you use type N on all the connectors that were used, like between
TX and ant ? They would all be cooking.
