WebThe class C Amp is what it is - an amp. The way I learned was your oscillator must be a preliminary stage. To set up the carrier. The amp at class C can be transformer coupled to an AM modulator usually in push pull. In plate modulation you need an average of 1.5 carrier watts added. So it's the audio modulation that's added by coupling to the Amp.
