LM324 based automatic voltage stabilizer circuit simulation
Dave, I just uploaded the file "MF_VCpot.zip". I got tired of trying to allocate floating net names to different pots. I chose the pin name as "PC", because it is the Pot Control pin. Feel free to Loo

Autotransformer deep questions!
Dave, Start your sinewave source ( V1 ) at some phase angle. 10, 20 ... 90 degree should resolve the loading issue. With 10 degrees, I have a 10 ohm load at node F and a clear sinewave. Mike
