The P12 is a stereo hybrid integrated amplifier. Each channel uses one E88CC and one 6N6 for the amplifier/driver section as well as special power transistors for the output. The valves (tubes) are specially selected in order to reach the best possible channel balance, noise and distortion values. Should you experiment with other tubes please notice that, due to the missing selection, the sound characteristics can be modified.
The P12 is, except for the 500 W transformer, built up completely dual mono. For the circuit we chose a three-step hybrid concept. As valves are excellent for voltage amplification and transistors for current. The combination of valves and transistors makes it possible to exploit the technical and sound advantages without having their disadvantages. For tonal reasons we abstained from overall negative feedback as well as from negative feedback in the transistor section, which leads, in our mind, to a particularly good sound.
The power supply is built up with an RC-filter. In combination with a high quality line filter, most of the line noise can be eliminated – the audio circuit works under the best possible conditions.
Switching of the inputs is effected by means of gas-filled reed relays. The only remaining mechanical contact is the volume potentiometer. We use the best potentiometers currently available - those from TKD.
Components have been determined separately in cooperation with long listening tests. Non-inductive resistors with only lowest tolerances, MKP, mica and oiled paper capacitors and high quality internal wiring are only a few examples of the final selection.
Even here our special patented measures for resonance elimination have been applied. They considerably reduce artificial artifacts and clearly improve the demonstration of finest detail resolution and room information
Thanks to all measures we reach a best possible stability and an ideal channel separation. The result is an extremely wide-ranging, airy, excellent structured, but nevertheless emotional sound pattern partnered with authority and solidity.
