Simulation isn't fast but if you let it complete and do an FFT on the last 30 seconds, it's 80dB down at all unwanted
harmonics.
There do however seem to be unwanted sidebands close in either side of 1KHz
Any suggestions for improvement?

Not that hard to make !

If you mean ASCII art, no thanks in the case of this circuit.

Easy to make a screen shot of your spice circuit and upload it one of those free image publication sites

You do not seriously expect readers to start ancient peesees and use millisoft widows emulators to run tea spices

These appear to be LTSpice, so why can't you use it to view my circuits?

 As I pointed out, am reading Usenet on a Raspbeery Pi4 8GB
Does everything here from spectrum analyzing to audio to video play
Why boot up an acient peesee to start a millisoft widows emulator
to look up some 80 deebee thingy that likely never has a practical use?
 

In any case if you can't simulate my circuits you won't be able to appreciate how brilliant a designer I am like Bill does.

 80 deebee makes me wonder if you not better spend your time on making e-bikes from vipes...

  And elteasprites simu is not worth a thing, reality is different from the models used.

Not all that different, and you can test a new idea in LTSpice a lot faster than you can cobble stuff together on the bench.

I stopped using it long ago (years).
My stuff works.

Because you don't try anything new?

ElTeaSprites is a bit like Hollowwood movies.

Hollywood movies are expensive. LTSpice is free.

Burb .. I mean Kirk.. well
I do not question your genius,

Sci.electronics.design does seem to be a genius-free space. There are quite a few competent people who post here, but genius is rare, and most of the people who are called geniuses have exploited a stroke of luck that let them look better than they deserve, though as Pasteur said, chance does favour the prepared mind.
Plowing through a lot of circuit variations quickly with LTSpice does give you more chances to win that particular lottery.
