BF469 to BF472 - a friendly warning

[Bonsai]

I have just spent about 3 days trying to work out why I cannot get my 1KHz distortion to under 0.02% on a sim.

Turns out its my BF4xx models.

I've plugged in some alternatives, and I'm down at 3-4 ppm.

(These are old discontinued devices anyway)

You mean they were too realistic? 😉

LOL

I hope not!

It is your simulator that getting down to ppm scale, not the distortion value.
Have you found out why cannot get your 1KHz distortion to under 0.02% on a sim.
