Do It Yourself (DIY) paradise for tube and SET project builders.

RE: You may have made a mistake with your modelling

This graph show the original 30Hz sine at the bottom.

If you count the peaks, you will see that the 2A3 is producing additional waveforms, some of which are out of phase with the signal.

If you follow it from left to right, sometimes the voltage swings in the wrong direction, compressing the relative crest.
Sometimes they double-up producing harmonics at a higher level then the intended tone.

lol I'm not sure what to call it, but it's not Hi-Fi!
