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.
