Do you know? IF the adjustments in a GE amp are actually Z matchers, and I believe they are, then I believe the GE instructions are wrong. A Z matcher's purpose is basically to maximize the efficiency of the amplifier. So with our repeater transmitter (VHF), which is two amps rated at 225 watts when combined, I adjusted them for minimum current draw at max power out. As you adjust, you'll soon find combinations that substantially reduce the current draw with no loss in power out. I've also added fans to the heatsinks and to the component side of all (3) amps in this transmitter. Power out is set to 180 watts and so far, zero trouble in 7 years. I admit that my experience with these amps is much more limited than yours, Nate, so my <luck> may catch up some day. Laryn K8TVZ
