Silbatone P-107 Stereo Power Amplifier

One might think it is totally out of character for Silbatone to create a 140 watt power amplifier. Fair enough, perhaps, since we are well known for resurrecting ancient super low power tubes and great advocates of the most sensitive horn speakers ever known to man. The social fact remains that there are legitimate applications for big amps. Some popular high end loudspeakers need this level of power to perform their best. Some very ambitious low frequency systems could also benefit. While we do not wish to condone mindless excess, the market for high power amplification has been somewhat under-served in terms of musical quality.

Silbatone decided to explore a new approach to meet this need, with results that doesn’t require explanations or apologies and technology owes little to what has gone before. Historically, attempts to marry tubes with solid state devices have been unsatisfying, to the point that the term “hybrid” scares most serious listeners away. Much of our research these past few years has been focused to develop successful unions of tube and solid state devices, as seen in out NeoHyb series and now in the P107 Power Amplifier.

The P107 Amplifier is entirely direct coupled, using an input transformer, a WE 310A triode voltage amplifier, and a unique I/V converter topology that sidesteps the soul-crushing issues usually encountered when trying to drive solid state output stages with vacuum tubes. The eliminations of coupling capacitors is achieved via sophisticated and stable servo level shifting methods that we perfected in earlier top-line designs. Basically, we reset the dialogue on high-power hybrid amplifiers by opening a completely new chapter in the history of the field.

The result of our efforts is big power with natural tube character. The P107 amplifier exhibits the grip and control of the best solid state amps yet it plays music with the heart of an artist. We anticipate that this genre-busting effort will convince even the most die-hard skeptic that there is promise in high-power hybrid approaches and open the door of Silbatone to a new category of high end audiophiles who prefer relatively power-thirsty modern loudspeakers. Big power without compromise, the Silbatone way!
