DAF40 Mullard

Description

The DAF40 Mullard vacuum tube offers outstanding performance for vintage radio restoration, combining signal detection and audio amplification in a single, compact component. Designed as a diode-pentode, the DAF40 became a staple in early AM radios, especially portable models that relied on low-voltage battery operation. Its two-in-one functionality simplifies circuit design while preserving sound quality and historical accuracy.

Mullard, one of Britain’s most respected vacuum tube manufacturers, built the DAF40 to exacting standards. Known for producing long-lasting and high-performance valves, Mullard ensured this model would stand the test of time. The tube operates on a 13V filament and integrates seamlessly into 1940s–1950s European radios, offering smooth signal handling and warm, analog audio output.

Restorers choose the DAF40 Mullard for its tonal integrity, reliable construction, and mechanical stability. Its rigid internal structure reduces microphonics and external interference, making it ideal for radios that require precision and durability. Whether you’re working on a collector’s radio or repairing a sentimental family heirloom, this tube helps bring authentic sound and operation back to life.

Its compatibility with equivalents such as the DAF41 or CV130 adds flexibility, but Mullard’s superior craftsmanship makes this version especially desirable. Collectors and technicians alike seek it out for its trusted heritage, vintage tone, and consistent performance.

As original stock diminishes, the DAF40 Mullard grows increasingly rare. Adding one to your toolkit or restoration project means investing in true analog history. Don’t settle for lower-grade alternatives—choose a valve that reflects the era it came from, with quality that still holds up today.

For authentic restorations, vintage audio purity, and dependable function, the DAF40 Mullard remains a top-tier choice. Experience the warmth and reliability of a classic tube made by one of the most iconic names in audio history.
