The output of a (driver) 110 watt amp is divided to feed two of these (although the driver amp runs at only about 35 watts out), then the outputs of the pair are combined for 225 watts. Yes, there are three amps with continuous duty heat sinks fed with two power supplies in these stations. I have no info on the G2 REV A, G2 REV B, or G4 units you have. Those would specify frequency split, production revisions, etc. 417524 is a continuous duty 110 watt 138-174 mc. amp. I do not have specific info on the Gx numbers, which may spcify the frequency split, etc. Laryn K8TVZ
