Phase Splitter
Hi,
Your circuit was interesting, so I ran a simulation in LTSpice, and I did not get the same values as you. To get the same current in the tubes I had to adjust the resistors in the ccs. My values for distortion, and Vout is different from yours, see attached pdf file. I got 30 p-p out for 1 v p-p in. And about -49db THD, which gives about 0.35%. If you look at the fft from the simulation, 3d harmonic distortion is the largest, at 30 v p-p out.
Tried with 12ax7 model to check, gave about the same figures.
But off course it's only simulation.
