"Another clue as to converter amps size is the set of reverse polarity fuses on it. EG a typical 55amper would have two 30a DC fuses. My 100amper PM3 has four 40a fuses. So I think a 75amper would have something in between.
Another possible clue is the size of the thermistor. The bigger converters have more of a thermistor. It is that black disc on two legs just in from where the 120v cord goes onto the circuit board near the 120a glass fuse. What is written on that thermistor? " (end)
I could not figure out which gizmo was the thermistor... no black disc with legs, and there is a short glass fuse pretty much dead centre of the board.
The two reverse polarity fuses are only 30a.
