BTW, as far as I can tell, below is the part of the tube's SUBCKT from dmtriodep.inc library modeling the heater:

Yes, that is the heater's model.? But there is also a "connection" from inside that netlist code, to the triode.? Presumably, that connection brings the heater's temperature to the triode, where it affects the triode's electrical characteristics.? I think many of the node voltages inside the heater model represent temperature, and there are thermal time-constants.
