I don't know how important they are I am not a FET ;) All I know is
the output transformer and the LP filter bank central toroid run a lot
cooler if the wave forms aren't all spiky. I hope someone can say how
critical this is? Nothing went pop, so presumably not ultra critical,
but heat = lost power I would think? Cheers G!
