TubePre
High Performance Stereo Single Ended Tube preamplifier

The TubePre is a high performance preamplifier board based on a single ended triode tube. TubePre is a complete preamplifier delivering ?audiophile? quality tube sound in a very small package. The board is small (only 100 x 85 mm), includes fully regulated DC power supply fro the tube heaters, and is powered with a standard and cheap power transformer that you can find in any electronic shop. Yet it gives to you:

- Stereo preamplification of audio signals with single ended triode architecture
- Class A operation
- No global feedback (ensuring the highest sound quality)
- Low output impedance (the preamp is capable of driving any reasonable load)
- Simple setup: only a standard 15 + 15 Volts AC power transformer is required, [you find it here].

Wiring the preamplifier board is a matter of 1 minute: you will need to screw the wires of the power transformer only. The unit comes with pre-soldered cables with RCA connectors fro input and output. The layout of input and output pins is described carefully in case you want to substitute the wires with your own.

"Tube Sound" is something that improves every HIFI system. Usually a tube preamplifier costs a lot of money, and is difficult to setup due to the need of specialized high voltage power supplies. In this case you get the high quality "tube sound" with an advanced audio architecture: the high voltages are generated on board. The power transformer is cheap and standard.

As usal the effect is impressive ... just try and you'll hear, tubes still rule the audio world!
