R438 is actually a 5.6k resistor shunted by a thermistor. Using an eductated guess that the
nominal value of the thermistor is 10k Ohm and so use a total value of 3.6k Ohm.

The node labels (eg. around the output transistors : N15, N10, etc.) are assigned by gnetlist
when it derives the netlist file from the schematic. A different tool chain will doubtless assign
different node labels.
