I know my post doesn't directly apply but every attempt I've taken with the fet amps splatter like crazy, I haven't tried this yet but it can't be too much better than the 75. Are the 2 fets in series or parallel? If they're parallel might be neat but mosfets are voltage controlled, at 13.8 volts these transistors just don't measure up, specially since its "probably" not all on the right freq. Fets are only good imo input and high voltage situation. After seeing the results myself for bipolar vs fet I know what I like, it would almost be more beneficial for them to make a 1 pill to fit in the sweet casing
