Jeff / Pico et. al - I've been watching this thread with great interest and learning a ton....
But... that video made my ******* week!!!!!
I hope everyone is happy, healthy and safe!

A friend was looking to possibly fab some Jammy Bridges so I fired the output stage PSU up and no smoke, no flames.

Hi Carsten,
It's saved with 5.99 (the in-development version of 6.0). I suspect you're on 5.1.5.
You can download the nightly development build from the website: Download | KiCad EDA. But be warned: it is in active development so the nightlies can be buggy. The plus side is that you can report bugs so we can fix them. 😉
If you're not a FSU (fearless software user) then I can back-date the file (but that has to be done by hand).
Cheers,
Jeff.

Hi Jeff,
thanks and you're right with the version.
Now I use the nightly (5.99.0-1455-gd3296d2ed) and it works well.
No, not needed. I installed on my "Play Mac" under macOS Catalina (latest beta). ;-)
Nice Design, looks good and thanks for sharing.

FWIW, there's a somewhat scattered list of new features in the nightlies here:

@Carsten, in PCBNew, double-click on the little colour boxes for front copper and back copper in the layers palette. Give them a bit of transparency; it will make it much easier to see what's going on. (I have front at 50% and back at 37% opacity.)
@Jeff,
top hint, looks better and easier to see, thanks!
Cool, global parameter!

Got a pair of my regulators built and on the bench.
Can't really tell much; the signal is way below the noise floor of my oscilloscope.
Interestingly, the voltage is a good 2+ V higher than SPICE predicted. Not sure what that's all about, but I'm not going to lose sleep over it.
The regulator loses its lock at about 212V line voltage. My mains is nominally 230V, but I think Jam said he normally designs for fluctuations of 10% or more?
The CRC resistor and series pass transistor are barely warm, so I'd probably be better off with a bit more source voltage (48V secondaries instead of 46V)?

Yes 15% it is. You can't get anything past Pico.
Jeff I am glad you are back.
