Infernal Noise Machine v1.1

Six months later (original post):

Infernal Noise Machine v1.0

The picture is of the v1.0. The v1.0 used an out-of-production case, the v1.1 is in a slightly different housing.

I am doing a limited run of five of the v1.1. Each unit is completely hand-made and is personalized on the jack panel. The I.N.M. is the flagship of our semi-pro gear, and is intended for studio use. More information at >the I.N.M. page<.

New ways to make noise

“How to make a Phantastron sing” article

Phantastron Schematic (Seely, 1950)

I posted a brief article on phantastrons and how to use them in audio synthesis on my Weblog at

Yes, there are schematics posted for the truly insane, and some suggestions to get you going. I was truly sad when I discovered that there really isn’t much info available on that great circuit of WWII radar!

Enjoy, and if you REALLY love it, you can feed me by getting a kit :). Maybe I’ll even cut you a deal or a swap if you’re a sufficiently deviant synther…

And, if you don’t already know, Electron-Tube Circuits by Samuel Seely and other old technical books are now in the public domain, and can be gotten at

Now, go forth and study! And do make something really tweaked, please.

Phantastron Kit Available

Electric Western is proud to present the Phantastron Kit: an all tube synth kit. The first all tube synthesizer extracted from Navy radar circuitry (at least that’s where I got it).

Here’s my video of testing the prototype model (yours will be prettier and sturdier) Audio starts as the tubes warm up (within 25 seconds) –

Video Demonstration:

Phantastron Under Test

First, I’ll start with what you don’t get:

1. A metasonix oscillator (yes it uses a 2d21 thyratron, and yes, I too love metasonix and Eric’s work, but this thing is different – the last thing I want to do is rip off someone else, really). But thank you Eric for introducing me to the 2D21, it does work better than the 884 in this case (although the 884 is sooo sexy looking)

2. 1V / xxx — the CV is quite variable, which makes this intstrument, well more like a trautonium than a TB303. Just watch the video above and know that the ribbon controls 0 to 5.5VDC linearly.


A Turret board with extra turrets for your own mods.

All the electronic parts, including a 2D21/PL21 thyratron and a 6SJ7 Pentode. Why these tubes? Well, the 2D21 is the most affordable thyratron and the 6SJ7 is a metal wonder that is RESONANT as heck in a phantastron circuit.

An all wooden box and 1/8″ Steel panels. Copper, brass and other shiny things.

A completed, safe power supply which reduces the possibility of tasering yourself and eliminates the possibility of working directly with AC wall current.

Instructions with theory lessons and the original scans of navy and pre-WWII tube textbooks. Drawings and and assembly guides. A nice note from me and my wax seal (yes, I am steampunk, and I do write the note with a quill pen on artisan paper).

All the fun of tubes and experimentation without buying metalworking tools, having a workshop, etc.

Oh, and please buy one, they’re pretty cheap, awesome, and I quit my job as an audio electronics professor and corporate employee to make more crazy stuff. The pitch ribbon is the next release, but if you’re really anxious, you can get a 500mm strip from SpectraSymbol at Spark Fun electronics and make your own. Or I can show you how to make one from $5 worth of EM shielding plastic and mylar. The Electric Western one will include some logic to change tuning, allow two touch finger control, analog computing and sustainable local lumber, etc.

Also, we are total “western steampunk”, post-apocolyptic mountain folk, and we use no lead, local materials, wind our own coils, never get Chinese circuit boards, use “green” canadian lumber and have a solar power array that makes 5KwH a day (and a steam engine that makes abut 9 watts), catch and use rainwater and live in an earthship, compost all of our feces and urine into bio-gas and humanure. And I really do wear a cowboy hat and I’ve punched a goat (lovingly). So, just buy one (a Phantastron kit, not a goat) to support our carbon neutral anti-corporate lifestyle (if that’s your thing).

Or just buy one and return it if you’re not happy. I can deal with that too. But you will be happy.

Here’s a time-lapse video of soldering the turret board:

Oh, and thank you to Eric and Metasonix for opening up the world to crazy tube instruments!
