The PV15 is a remote-controlled vacuum-tube preamplifier designed to serve as the control center for high-performance audio and audio/video systems. The PV15 features a sophisticated level control circuit designed to allow precisely repeatable level and balance settings. With seven inputs , the PV15 will accommodate elaborate audio systems. The PV15 includes a Theater Loop which provides a locked unity gain setting, making it the ideal component for listeners who've been wanting to integrate home theater into their stereos without compromising the performance of their primary music system.

The PV15 zero-feedback line-stage circuit consists of a single-ended triode amplifier using a 6C4 miniature vacuum tube. A direct coupled buffer stage provides a low output impedance to insure that the PV15 can comfortably drive virtually any combination of interconnect cable and power amplifier. This circuit's simplicity pays dividends in tonal integrity and seductive musicality while offering flexibility in system matching.

The PV15 is optionally available with a built-in phono equalization preamplifier stage to provide the additional gain and RIAA equalization that phono cartridges require. The phono circuit uses two triode amplifier stages for voltage gain. A passive network of precision components accurately provides the required frequency compensation. A direct coupled buffer stage isolates the stage from external cables and components connected to the EPL and theater outputs. The circuit employs no negative feedback loop, eliminating feedback induced timing errors that compromise dynamics and imaging. The resulting circuit is a simple, low-noise, high-gain device well suited for use with a wide range of phono cartridges of both moving magnet and moving coil types.
