The legendary G2504 (also known as RGN2504) full-wave rectifier valve from Valvo, manufactured in Germany during World War II under strict military specifications. This is the iconic wartime version produced in week #44 of 1942, bearing the official Wehrmacht eagle stamp and approval mark “W” on the glass — a guarantee of quality for critical radio and radar equipment.

Built for the German Army, this ultra-rare rectifier features massive black large mesh plates, an upper cup getter, and a rugged black phenolic base. Its robust construction and low internal resistance made it ideal for high-voltage, high-reliability applications in field communications and command systems.

Key historical and technical features:

• Official Wehrmacht markings: eagle + “W” approval stamp on glass
• Production date: week 44, year 1942
• Large black mesh anode plates for superior current handling
• Top-mounted foil cup getter — signature of Valvo’s wartime design
• Military-grade vacuum integrity and filament durability

Today, the G2504 is prized by collectors and high-end amplifier builders for its exceptional sonic performance, low hum, and historical significance. Each unit is individually tested for emission and voltage regulation over original military specs.
