- JFET/BJT CFP looks attractive but results are sonicaly disappointing.
last time I tried one it oscillated at 98MHz. How good is your CRO?
The distortion of 0.05% to 1 KHz is in maximum power?
You can use the input differential pair that should reduce the distortion.

I did not like the output with electrolytic, very ESR in 20KHz
simulation will not show it .

Alrighty then, I did it. A little rough but it will do for the first complete prototype:

Silkscreen is printed on the other side. I'm taking tomorrow off so I may do a bit more with it - drill holes, add parts, etc.
Good work, I also use the contour GND...
