Experience the Manley Neo-Classic 300B RC, single-ended triode preamplification

The Manley Neo-Classic 300B RC Preamplifier employs the 300B triode as a dedicated line driver in single-ended Class A configuration, combining vacuum tube rectification and regulation with advanced ripple rejection circuitry for exceptional noise floor performance. Hand-assembled in California, this all-triode design delivers the transparency and dimensional imaging characteristic of zero-crossover-distortion amplification while providing comprehensive source integration and remote control functionality for modern high-fidelity systems.

Pure Class A triode topology with tube-regulated power supply

The preamplifier architecture maximizes the linearity and bandwidth of the 300B triode in single-ended operation. Vacuum tube rectification and regulation, combined with proprietary ripple rejection topology, achieve exceptionally low noise performance essential for resolving micro-dynamic information and spatial cues. The all-triode Class A signal path maintains phase coherence and harmonic accuracy from input to output, ensuring faithful reproduction of source material without solid-state artifacts.

Integrated headphone amplification with impedance optimization

The 300B output stage functions as a dedicated Class A headphone amplifier, delivering 1 watt into 600 Ohm loads with exceptional current drive capability. A three-position impedance selector optimizes output matching for headphones ranging from 30 Ohms to 4000 Ohms, ensuring proper damping factor and transient response across all driver types. This topology provides reference-grade headphone performance directly from the preamplifier without additional amplification stages.

Comprehensive connectivity with motorized remote control

System control is executed through a precision motorized ALPS volume potentiometer operated via omnidirectional RF remote, providing wireless functionality through walls and cabinetry. Five line-level inputs accommodate multiple sources, while a dedicated unbuffered record output and post-volume subwoofer output enable flexible system integration. The Neo-Classic 300B RC serves as a complete analog control center for discerning high-fidelity installations.
