ECC85 Philips

Description

Compact Dual Triode for RF Applications
The Philips ECC85 is a miniature double triode vacuum tube specifically designed for high-frequency circuits, such as FM tuner front-ends and oscillator stages. It contains two matched triode sections in a single glass envelope. This design allows balanced signal processing and clear, low-noise amplification. Because of its precise electrical characteristics and compact size, the ECC85 remains a favored choice for vintage radio restorations and custom RF equipment.

Stable Gain with Reliable Oscillation
Each triode section delivers consistent gain with minimal distortion, which ensures clear and steady frequency reception. Moreover, the ECC85 performs efficiently at VHF frequencies, maintaining strong signal integrity in tuner front-ends. Philips’ high manufacturing standards reduce microphonics and internal capacitance, thereby enhancing oscillator stability. Additionally, the tube withstands continuous operation without performance loss, providing dependable amplification in sensitive RF circuits.

Versatile Format and Broad Compatibility
Equipped with a 9-pin B9A base and slim glass envelope, the ECC85 fits compactly into chassis common in radios and test instruments. Therefore, it serves as a direct replacement for similar ECC85 tubes. Whether restoring vintage FM radios or building custom front-end circuits, the Philips ECC85 installs easily and performs reliably.

Trusted Philips Craftsmanship
