    So I "think" I've found a suitable replacement mosfet final for the original that let the smoke out on my 980 plus https://www.mouser.com/ProductDetail/NXP-Semiconductors/AFT05MP075NR1?qs=RnZx02BLotIGApUaCX%2B4pw== ... My biggest question is should I replace any other parts or mosfets while I'm in there? I watched a YouTube video on radio finals repair and they said to replace an AM mosfet as well while you're at it because it takes a huge hit when you toast the finals and half the time those burn out a few months later anyway... Also, anyone know where I can find a schematic, I've looked high and Googled low and come up empty?! Also, the factory seems to put an inglorious amount of solder on the right side of the finals on the couple I've seen, is that really necessary? Thanks in advance, 73...[​IMG]
