ECH84 Haltron

Description

Reliable Triode-Heptode Converter
The Haltron ECH84 is a triode-heptode vacuum tube designed specifically for frequency conversion in FM tuners and RF stages. As a result, it plays a key role in signal mixing and oscillation in vintage radios and communication equipment. This compact tube provides smooth, stable operation in circuits that require efficient signal handling and minimal drift.

Efficient Frequency Conversion Performance
The integrated triode section acts as a local oscillator, while the heptode handles mixing duties. Moreover, the ECH84 delivers clean frequency translation with excellent separation and low noise. In addition, its internal design minimizes spurious signals and distortion, resulting in clear intermediate-frequency output. Consequently, it performs reliably in both domestic and professional-grade receivers.

Compact Design, Broad Compatibility
The ECH84 features a standard B9A 9-pin base and compact glass envelope, making it easy to install in tight layouts. Therefore, it’s well-suited for slim-profile radios and FM front-end circuits. Furthermore, it can replace compatible converter tubes in a wide range of European and UK-made equipment. Whether you’re maintaining a classic tuner or refurbishing a communications rig, this tube ensures seamless integration.

Haltron Craftsmanship and Durability
Haltron tubes are known for their consistent performance and solid construction. The ECH84 includes rugged internal structures and durable pins for long service life. Additionally, it resists microphonic noise and maintains signal integrity even under extended operation. As a result, you can count on it to perform with accuracy in vintage restoration projects or modern custom builds.

Perfect for FM and RF Projects
Whether you’re repairing a vintage stereo tuner or building a frequency conversion stage from scratch, the Haltron ECH84 offers the stability, clarity, and reliability you need. Choose this tube for its compact versatility, smooth performance, and trusted Haltron engineering.
