SC12 – Triode Pre-Amplifier
Simply uncompromising.The SC12
What happens when we develop a preamplifier from ground up with the objective of zero tolerance policy in terms of design compromises and with the goal of achieving the ultimate musical performance?
SC12 is the answer.
All components which are critical for the end result, are manufactured especially for this preamplifier and let us just name a few:
Hand made line output transformer; power transformers for each voltage line with specially paper in oil power supply capacitors.
Every potentiometer, switch, regulator and controller is custom made for us by Elma Switzerland and here we would like to point out the volume potentiometer to illustrate the level of quality. It has 48 steps and can thus adjust the volume levels ultra-finely.
Appearance, of course, is of the outmost importance so front panel and all the knobs are handmade from the best aircraft grade aluminum, being cut to the extremely small tolerances and later on hand polished to achieve one of a kind look.
In all our products we are very passionate regarding the use of directly heated triodes (DHT), as our standpoint is, that without them, ultimate expression of music reproduction would not be possible.
In case of SC12, our tube of choice in the output is extremely fine and musical NOS VT25 tube, working hand in hand with specially developed and hand made line-out transformer. Tube rectification is being done by legendary NOS 274b tube.
With all said, we strongly believe that we managed to create one of a kind preamplifier which deserves your attention.

PRODUCTION AND PHILOSOPHY
I live and work in Central Switzerland next to beautiful Lake Lucerne, surrounded by mountains. Empowered by my wonderful family, I work with a team of unique experts to make those audio dreams come true. I take a lot of time to develop and manufacture high efficiency coaxial speakers, tube amps and DACs. Deeply rooted in audio history, I am also fully aware of today’s manufacturing advantages and apply them whenever they will be useful. Please take your time to experience my components and I can promise you, it will only take moments before you realize that you are listening to something special, something musical: a gateway to the music. Let me introduce you to some secrets behind the making of these products.
We at Tobian Sound Systems believe that the beauty of our audio products lies in the hands of the makers. I may be the originator and driving force, but the products have more than one father.
Our wire is very slowly dragged and carefully isolated with natural resin and then baked. The next step is the alignment of the wire on the core. The core of the transformer is made of a special, grain oriented steel, that only one company in the world makes – in Switzerland. Each layer of oval-section wire is then hammered into one homogenous surface. It is along the outside of this augmented surface that the signal will travel. Each layer is then isolated with mu-metal shielding before the next layer goes on. After a transformer is finished, it is submerged in natural resin, and baked. Every step of the process, the materials, the execution, the duration of each phase, the precision that only comes from experience, turns these transformers into something you cannot just buy. You have to be dedicated to have them made like this. It’s as if they are dreamt into reality. Put your hand on one of those transformers while the amp is on – are you sure it’s really on? You cannot tell. Like driving a Bentley: only when you look at the dashboard do you realize how fast you are really going.
