TUBE-1006
Six-Valve Class A Tube Output Stage — Analogue Warmth for Digital Sources
Descripción ⌄
GoldNote Tube-1006 — tube output stage module. Compact valve output stage with six 6n1p Class A tubes in a proprietary Totem-Pole configuration, adding warmth and dimensionality to digital sources. Compatible with Gold Note CD, DAC and preamplifier products via dedicated Tube input, with simultaneous RCA/XLR line input from third-party sources. Same ultra-wide bandwidth design as the Tube-1012 in a more compact chassis.
Technical background
GoldNote power amplifiers use proprietary Optical BIAS control — monitoring output transistor bias continuously via infrared sensors rather than mechanical trimmers — for drift-free long-term stability across all operating temperatures. Selectable damping factor (250 or 25) adapts bass control to different speaker types. The P-1000 mkII preamplifier adds three independent linear power supplies filtered by military-derived noise-cancelling coils, and a 100-step ALPS optical encoder volume control with 0.5dB resolution.
Design story
GoldNote's amplifier development has always prioritised long-term real-world stability. The Optical BIAS system — developed after observing that conventional bias trimmers drift with temperature and age — continuously corrects output transistor operating point using infrared sensors. The P-1000 mkII chassis is machined from a single aluminium billet, with three fully independent power supplies filtered by coils derived from helicopter avionics noise-cancellation technology, making it the most mechanically and electrically isolated preamplifier in the GoldNote range.
