The legendary G2004 (also known as RGN2004) full-wave rectifier valve from Valvo, manufactured in Germany during the early 1940s under strict military specifications for the Wehrmacht. This ultra-rare wartime rectifier features massive black large mesh plates, an upper foil cup getter, and official Wehrmacht eagle markings with approval stamp “W” on the glass — a guarantee of quality for critical radio, radar, and field communication equipment.

Built to endure extreme conditions, the G2004 was selected for its exceptional voltage stability, low internal resistance, and rugged construction. Its robust design made it indispensable in German military electronics throughout World War II.

Key historical and technical features:

• Official Wehrmacht markings: eagle + “W” approval stamp on glass
• Production era: early 1940s (wartime)
• Large black mesh anode plates for high current handling
• Top-mounted foil cup getter — signature of Valvo’s military-grade production
• Original black phenolic base

Today, the G2004 is highly prized by collectors and high-end amplifier builders for its sonic purity, reliability, and historical significance. Each unit is individually tested for emission and voltage regulation over original military specifications.
