I'm repairing a Mirage B3060 Brown face that was reportedly inoperative. It seems to work fine except for 2 issues. 1) The amp will put out full power on the high end of 2M (146-148) but around 40w less on the low end (144-145). How can I average it out over the entire FM portion or even the whole band? 2) During a visual inspection I found a wire or what might have been a component burnt off between the Antenna socket ground and the circuit board. See attached photo. I pulled the wire further apart for a better view. The original burnt gap was approximately 1/16"+/-. This amp is used by my Dad who has a bad habit of disconnecting the coax from the radio which still leaves the amplifier and SWR/power meter connected to the antenna. I keep suggesting he just disconnect the antenna coax from the meter, thus removing all components and isolating the antenna, but he never listens to common sense He did have severe thunderstorms in the area, so the burnt area might be related yet the meter and amplifier still function. I checked online for a schematic and only found a copy on the BAMA site that was blurry and somewhat chopped off where I need to view it. Mirage/MFJ website doesn't go back far enough for this amp and the newer amps are not showing what I need. Can anyone clue me in to whether this was a simple wire or possibly a diode? Is there a better schematic out there? I have read articles mentioning a 4 page schematic/manual but the links are dead. Any ideas to even out power output across the band? Thanks in advance.
