This would be for single final mosfet in the current edition 959. We all know they can be modded-peaked for the neighborhood of 30-35 watts. But there's much more to it than turning the power pot. Several things have to be done. Anyone know the whole procedure? Yes there is a Service Manual at cbtricks but that's just for achieving factory specs. Doesn't help with the full power-peak modification. This is not for my 959. It has already been done. There are several guys in my area that are considering this radio. A local pro tech at a truck stop in the area is the go-to guy to get these things stroking but of course he won't tell anyone how to do it. TNX !!
