Edward Rawde posted an eight-transistor low distortion sine wave 
oscillator circuit recently, and John May pointed out that you could 
leave out half the transistors.

I couldn't immediately see exactly how either of the circuits worked, 
though I could get the simulations to run under LTSpice and see roughly 
what was going on.

I've now dug a bit deeper. Here is a five transistor version of John 
May's four transistor version.
