Timeline for LTSpice is frustrating me. Why isn't this Class C amplifier working? I can't get a sinusoudal output

| Aug 10, 2018 at 22:11 | comment | added | niko20 | @ThePhoton ya..but actually, this isn't supposed to be linear. It's supposed to turn on HARD and then off, and the tuned circuit it supposed to fill in the rest. | |
| Aug 10, 2018 at 22:10 | comment | added | The Photon | Notice your output amplitude is now only about 0.4 V peak-peak, not 40 V like before. It's a lot easier to keep a circuit linear with a smaller signal swing. | |
| Aug 10, 2018 at 22:10 | comment | added | niko20 | Bah nevermind, this was because my carrier was only 1V p-p so the mosfet wasn't fully turning on I don't believe. If I up the sine voltage to 6 volts I get the same bad waveforms as with the BJT. | |
