Quote from: KMG on September 26, 2012, 02:56:32 AMAccurate emulation of grid current (shift of operatin point) often means more than a shape of clipping.Look how tube stage respond on "burst" input signal.
Quote from: KMG on September 26, 2012, 11:30:58 AMAdding servo you'll loose most benefits of jfet stage. In this case it'll sound like simple opamp with clipping diodes.Simpler tunung but poorer sound.
Quote from: LoudthudIt's a servo to set the operating point of a JFET so you don't need a pot....The bias adjusts perfectly changing the supply from 9 to 32V.
QuoteI use diode clipping on the input because gate current causes the output to clip too sharply and gate current doesn't always start when the output clips.
Quote from: Loudthudtell me why the opamp doesn't oscillate
