A "must-have" for every Steampunk-Enthusiast or anyone interested in vintage technology, electronic music or lover of handcrafted electronic instruments.

The Theremin was the first electronic musical instrument invented by Russian phisicist Leon Theremin and celebrates it´s 100th birthday next year.

Therefore we wanted to recreate a small but nevertheless playable and fully working Theremin with as much of the original (vintage) technology as possible.

That´s why we settled on using vacuum tubes instead of modern-day IC´s (which all the other Theremins on the market do use).

There is not a single IC involved and the only pieces of silicon are three transistors to create by means of a ring-oscillator the 40VDC anode-voltage for the tubes (plus 1 or 2 diodes). Because we only use 12V DC for the tube heaters the Tube-Theremin is absolutely safe concerning electric shock (contrary to what first comes to mind when thinking of vacuum-tubes with their often hundreds of Volts supply voltage).

We also wanted to make the Tube-Theremin look beautiful so that it can be a bit of an eye-catcher when presented on a show or just sitting on a shelf in your living-room, lab etc. 

We have already presented the Tube-Theremin on 2 HAM-conventions (without any marketing and without telling people what it was). It was recognized instantly as a Theremin and every spectator wanted to play with it.

You get the special earth-connected power-supply with the fitting power-chord/power-plug for the following countries:  Europe, USA, UK, Suisse, Australia, China, Italiy, Japan.

Because the power-supply has a standard IEC-Connector you get a power-chord for almost every country in the world not listed above.

The story of the development of the "Tube-Theremin" is on the following web-pages (only in German):

 Theremin Pt.1 

 Theremin Pt.2 

 Theremin Pt.3 

 Theremin Pt.4 

Risks and challenges

Although we mostly avoided any special-purpose parts there could a shortage of the supply with the tubes or other parts for the Tube-Theremin. We have asked the suppliers beforehand if they have enough parts in stock to satisfy a run of 50...100 units.
Nevertheless some parts could have a longer lead-time or have to be replaced with compatible parts.
There could be delays by illness or unforeseen problems in manufacturing especially if the campaign massively overruns it´s goal.
There could of course be a bandruptcy of our company by unforeseeable events, through other reasons or by a gross miscalculation of the necessary parts- and labour-costs.
