The legal limit is 1500 out, why else use a 4-1000. he asked about class C,
a far larger grid swing. if he wanted linear for AM. then the 4-1000 makes
sense, but why fool with that unless designed for legal output. And you
just proved the drive point on your amp. 30 watts for 375 out and on peaks
it takes 140 watts. Bernie W8RPW
