This just reworks my circuit to use a controllable asymmetric current mirror instead of the FET for gain control. I take the
feedback from the full wave rectifier and switch every half-cycle to reconstruct a variable amplitude sine wave to control the
output amplitude. It does use a lot of components, but it strikes me as fairly comprehensible.

The circuit just copes with worst case capacitors - 15.15nF and 14.85nF - at C5 and C6, as it was intended to do. Using a trim
pot to take out component tolerances would let you get away with a smaller correction signal injecting smaller doses of the odd
harmonics.

The circuit does cry out for monolithic dual transisors.The On-Semi

There was a dumb error in the original circuit. The two transistor switch (Q5 and Q6 in the original circuit) that turned the
full wave rectified waveform back into a sine wave was set up with very little headroom. It didn't stop the circuit from working
as intended after it had settled down, but it made start-up a bit tricky.

Here's the corrected version. It's performance isn't noticeably different

I've taken Edward Rawles commnents to heart,but I suspect he has inadvertently corrected the circuit into something that simulates
a lot slower that the circuit I'm looking at, which runs at about 30msec/sec.

I've corrected the right transistor to Q6. I've played with the text file in an attempt deal with the line feeds.

The \n+ character string does seem to be the way WordPad deals with line wraps in the .asc file.

It's been many years since I forgot that WordPad even exists.
Get yourself a real editor: https://notepad-plus-plus.org/
I use it for editing files on both Windows and Linux (Over WinSCP).
It may be worth noting that WordPad (which I just opened for the first time in seems like centuries) has a No wrap option under Word
wrap.
I'd set it to No wrap before pasting it into a post.

Deleting .ENDS from the end of the model string may be one way of keepig LTSpice happy, but it probably isn't the right one.

Then please tell us what the right way is when you get to testing LTSpice 24.1.0
