From Klyne web site: :
The Model 7PX3.5 Phono Preamplifier (the lower unit in the photo) is designed for the person seeking the ultimate in phono reproduction. A complete stand-alone phono preamplifier with an external power supply, it can be used with a line level preamplifier, a digital preamplifier with an analog line level input, or a passive switchbox controller. Like that of our other audio components, the sonic character of the 7PX3.5 emphasizes musical naturalness rather than the overly dramatic “high fi” sound with exaggerated definition and consequent fatiguing high-frequency reproduction. The exceptional neutrality of the 7PX3.5 enables it to mate equally well with either vacuum tube or solid state preamplifiers.
Consistent with our commitment to a musically natural sound, all signal amplification is accomplished with our discrete proprietary circuits potted in modules labeled Music Module™. While we hold technical excellence in the highest regard, our final choice in circuits and components for the Music Module™ is based on their ability to accurately reproduce the correct tonal and harmonic character of music itself. Furthermore, each Music Module™ is constructed and adjusted for its particular function in the circuit.
All critical passive parts in the 7PX3.5 (jacks, wire, resistors, etc.) have been selected on the basis of extensive listening evaluation in our own reference system and are chosen primarily for their ability to yield the most transparently natural sound at all frequencies. (Some of the parts are extremely expensive aerospace components rarely used in consumer grade equipment.) • RIAA Equalization is passive using the very finest parts available.
• The external power supply uses a toroidal transformer with a capacity approximately 5 times the actual preamp power consumption. It provides filtered dual-polarity DC power to the main chassis via a shielded power cord and a premium-quality screw-lock connector.
• Internal power-supply regulation is accomplished with three precision cascaded levels. The first level provides ripple and line transient filtering, and locks to a nominal DC level. The second and third levels use individual precision feedback regulators for each channel which independently feed the first and second amplification stages via “star” networks. This trilevel regulation system, consisting of a total of ten independent regulators, provides a very high level of channel separation.
• Main outputs are direct coupled to eliminate the need for large blocking capacitors in the signal path. DC offset is maintained to plus or minus three millivolts with DC servo circuits operating outside the signal path. All inputs and outputs are protected with shunting diodes.
• Separate buffered tape outputs are provided for the ultimate purity in taping cherished analog pressings directly to either analog or digital tape recorders without the need to route the signal through a companion preamplifier.
• The Model 7PX3.5/B includes a factory installed balanced output option (similar to the Model 7LX3.5). :
