Also, what's up with the spice integration in KiCad anyways? It seems nice enough to not be just an afterthought, but where are the spice models? It doesn't ship with anything, not even the most generic jelly bean parts. Do they really expect me to dig up everything on my own? Never heard of "batteries included"? Maybe I missed some magic kicad-spice-models package. The closest I could find is this inofficial git

This brings me to something I need to figure out:
I got a heterogeneous bunch of Linux boxes and a whole spectrum of weird and odd software. Stuff pulled from git, random tar ball sources, binaries, the odd .deb file, and a bunch of wine prefixes and python venvs. Maintaining that is a nightmare. Especially so across all my systems.

So far I have an ad-hoc mix of local installations and things on my central nas. But, as I said, it's a nightmare.
I need to streamline it. Maybe keep everything central on the nas, and use rsync to pull it onto my laptop for mobile use.
But that leaves me with the problem of differences in the host OS. Maybe I could make a chroot with a minimal debian or ubuntu I build against. My skin crawls at the thought of X11 or desktop integration.
Before you mention docker: No. I want no abstraction layer between me and the files.

I'll look into nix.
Alright, we are up and running! Finally. Only had to also compile ngspice.

I really need to streamline all my manually installed programs soon. For now, let's press on. I hope this blows LTSpice out of the water. Being a native Qt6 app is already a huge perk.

It's $current_year, WHY ON EARTH do you not implement a theming engine? It took KiCad ages to finally do it. Now I'm being teleported back to ye olden days with Qucs-S. No, this is even worse, because the only customizable elements are the background and grid. You cannot set the foreground color. The heck.

First crash of the day while dragging a part 👌
At Finger I rescued this modified Kosmos XN baseplate. Interesting idea to modify them into something more useful. They sure do make for a nice test fixture. Been wondering what the circuit is.

9 pin noval with pin 9 not connected. 12V heater voltage, so if it's a 6.3V tube, it must have two heaters that can be connected in series. That and the pinout already suggest a double triode like the ECC81, 82 or 83. The varicap and ten turn pot must be part of some form of tuned RF circuit. So maybe an oscillator or filter. The screw terminals look like they would house a big air wound coil with tap. The transformer lives at the anode side of the second triode, if it's a double triode tube. It's too clunky to pass through any RF, so that rules out it being an oscillator+buffer. Instead the second triode looks like an audio stage. That made me think audion style receiver.

And indeed. Someone was making and selling these in the 2000s. Clone of the Kosmos Radiomann electronics kit that saw a re-release around that time.
