ECF80 Ultron

Description

Versatile Triode-Pentode for RF & IF Stages
The Ultron ECF80 is a compact vacuum tube combining a triode and a pentode in a single envelope. Designed primarily for RF and IF amplification and oscillator-mixer roles, this dual-function tube offers exceptional versatility. Because it unifies two active sections in one unit, it saves space and simplifies circuit design—especially in vintage TV tuners, radio receivers, and communication equipment.

Reliable Gain and Signal Clarity
The triode section of the ECF80 excels as a local oscillator, while the pentode handles high-frequency signal amplification. Moreover, both sections operate with low noise and consistent gain, making them suitable for applications demanding high stability and clarity. Ultron’s reliable construction ensures dependable performance under varying loads. Consequently, you’ll experience fewer signal dropouts and distortion across sensitive frequency bands.

Compact Format and Broad Utility
Featuring a standard 9-pin Noval (B9A) base, the ECF80 fits easily into compact layouts typical of European radio and test gear. Additionally, it serves as a direct substitute for equivalent types such as 6BL8 or 6U8. Whether you’re restoring classic electronics or building a new hybrid RF circuit, the Ultron ECF80 offers seamless integration and dependable function.

Ultron Craftsmanship You Can Trust
Ultron vacuum tubes are known for precision manufacturing, solid internal structure, and electrical consistency. The ECF80 reflects this tradition with stable interelectrode spacing and rugged materials. Furthermore, it resists microphonic interference, thermal drift, and aging artifacts. Therefore, engineers and enthusiasts favor Ultron tubes for durable and long-lasting builds.

Ideal for Vintage and RF Projects
Whether you’re reviving a mid-century radio or designing a modern signal mixer, the Ultron ECF80 triode-pentode offers clean gain, oscillator strength, and layout efficiency. Thus, it’s the perfect choice for projects where performance and compactness must go hand in hand.
