Gold Note Tube Output Stage

The Gold Note Tube Output Stage is designed to introduce the unmistakable warmth, dimensionality and harmonic richness of valves into high-performance audio systems. Created to work in perfect synergy with Gold Note electronics, these external Class A output stages elevate already exceptional sources and amplifiers to an even higher level of musical realism.

While solid-state designs provide precision, speed and control, the addition of a dedicated valve stage enhances tonal colour, depth and natural flow. The result is a presentation that feels more organic and emotionally engaging, without sacrificing detail or authority. For listeners who value the expressive character of vacuum tubes, this is the definitive upgrade for achieving a truly immersive High-End listening experience.

Proprietary Totem-Pole Class A Architecture

At the heart of both models lies Gold Note’s proprietary Totem-Pole output stage design. Each tube operates within six independent audio stages, delivering ultra-wide bandwidth and exceptionally low distortion. With THD+N as low as 0.0028% at 1kHz and a signal-to-noise ratio exceeding 100dB, the circuit ensures purity, stability and refinement.

The design provides a modest 2dB gain, maintaining system balance while enriching tonal texture. Output impedance below 600Ω ensures excellent compatibility with preamplifiers and power amplifiers requiring loads above 10kΩ. This carefully engineered architecture guarantees that the addition of valves enhances musicality without introducing unwanted colouration, preserving clarity while adding body and dimensional depth to every performance.

Flexible Connectivity and Seamless Integration

The Gold Note Tube Output Stage offers versatile connectivity for effortless system integration. On the rear panel, you will find balanced XLR and unbalanced RCA line inputs, along with a dedicated 5-pole XLR “Tube In” connection designed specifically for compatible Gold Note sources. This allows simultaneous connection of two different sources, selectable directly from the front panel for maximum convenience.

Maximum input levels reach 6Vrms via RCA and 12Vrms via XLR, while outputs extend to 8Vrms RCA and 16Vrms XLR with distortion kept below 1%. A Super Linear Vacuum Tube Regulator power supply, featuring four inductive choke filters, ensures exceptionally stable voltage delivery and ultra-low noise performance.

TUBE-1012 - Flagship 12-Valve Performance

The TUBE-1012 represents the ultimate expression of Gold Note’s valve output stage technology. Equipped with twelve 6N1P valves operating in pure Class A, it delivers enhanced scale, authority and harmonic complexity. The greater valve count allows for increased headroom, improved microdynamic expression and a more expansive soundstage presentation.

Weighing 16 kilograms and housed in a substantial 430mm-wide chassis, the TUBE-1012 reflects its robust internal construction and premium components. With power consumption rated at 80W, it provides consistent thermal stability and performance. For those seeking the most immersive and luxurious valve character, the TUBE-1012 offers the highest level of refinement and emotional engagement within the range.

TUBE-1006 - Elegant Six-Valve Refinement

The TUBE-1006 offers the same proprietary Totem-Pole design in a more compact six-valve configuration using 6N1P tubes. It delivers beautifully balanced warmth, smooth midrange textures and enhanced spatial depth while maintaining impressive control and transparency. Weighing 13.3 kilograms, it shares the same build quality and Super Linear regulated power supply architecture as its larger sibling.

The TUBE-1006 is ideal for listeners who desire the sonic benefits of valves with slightly lower system complexity and a more streamlined presentation. It integrates effortlessly into both balanced and unbalanced systems, offering a refined, natural sound signature that enhances musical intimacy without overwhelming the system’s inherent character.

Engineered for Musical Synergy

Both versions of the Gold Note Tube Output Stage are engineered to complement and elevate compatible electronics rather than replace their inherent strengths. They preserve the control, speed and precision of solid-state amplification while adding the fluidity and harmonic richness that only valves can provide.

The combination of advanced Class A design, stable regulated power supply and carefully selected components ensures long-term reliability and consistent performance. Measuring 430mm wide and 135mm high, each unit integrates seamlessly into full-width High-End systems.

Whether choosing the commanding presence of the TUBE-1012 or the elegant refinement of the TUBE-1006, this upgrade transforms your system into a more natural, engaging and emotionally compelling musical experience.
