VALVET E4 Single-Ended Class A Mono Power Amplifiers (Pair) The VALVET E4 mono power amplifiers are designed to deliver music in its purest, most natural form. Built around a simple yet highly refined circuit, they prioritise short signal paths, premium components, and a direct connection to the music—resulting in an engaging and emotionally rich listening experience. Operating in true single-ended Class A mode with a single output transistor, the E4 achieves a level of musicality and charm rarely found in other amplifier designs. Despite their modest power rating, they perform exceptionally well with efficient loudspeakers, delivering dynamic, balanced, and highly expressive sound. Combining the tonal beauty of single-ended tube amplifiers with the control and reliability of solid-state design, the E4 offers the best of both worlds—without the drawbacks of valve wear or reduced bass control. Key Features: Single-ended Class A mono power amplifiers (pair) 12W into 8 ohms / 20W into 4 ohms Single output transistor per channel for maximum signal purity Ultra-stable power supply with 500 VA toroidal transformer High-speed rectification with 4 x 60A diodes Discrete Class A operational amplifiers Extremely short signal paths with pure silver wiring Tube-like musicality with improved control and reliability Dynamic, balanced, and highly expressive sound Connections: Line-level input Speaker outputs What’s Included: Pair of VALVET E4 Mono Power Amplifiers Power cables Manufacturer packaging Note: These Class A amplifiers generate heat during operation and are best paired with efficient loudspeakers for optimal performance. Ensure adequate ventilation during use.
