The current version has been running overnight and has got to three
seconds, and the DFT from 2.8 to three seconds shows third harmonic
about 90db below the fundamental. The noise floor is about 100dB down
and the other harmonics are barely visible above it.

Here's the .asc file. There are extra components put in to make it
simulate faster - L1 and L14 are the obvious examples, but L10, L11 and
L12 got put in for the same reason. I suspect that if I had put in
equivalent series resistance and inductance for C22 as well as for C6
and C15 I might not have needed some of them.

There is some other tidying up I could do, and that should get get the
simulation speed up. I got a new circuit from John May last night, and
it not only spits out a very clean sine wave but also simulated very
fast. I forgot to put it on solid state disk before I ran it, and it
took as long to get one of the waveforms off the spinning hard disk as
it had done to run the simulation.

Ny tidying up is going to wait until I've got ten seconds worth of
simulation out of the current circuit, and can look at the details of
what's going on deep in the circuit

When evaluating architecture there's little to be gained by using a
complicated opamp model.  Use a simple 1 or 2 pole model to begin
with.

Try the attached file, I've used a simple model to speed up the
simulation, and made a slight circuit change.  This shows the
harmonics due to the control loop to be sub 130dBc.  Of course the
amplifier harmonic distortion is not simulated, but neither was it in
the simulation by Mr Rawde.
