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.

73, Mike W4EF......................

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.
