A relative of the phase shift oscillator is the Wein bridge oscillator, which includes a non-linear element to control gain so the active device(s) don't clip. These oscillators can give a good quality sine wave (low harmonics) with few parts. A Royer oscillator can also do so, but requires more specialty parts to build. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
