ECC91 Triotron

Description

Compact High-Frequency Dual Triode
The Triotron ECC91, also known as 6J6, is a miniature double triode vacuum tube ideal for RF and analog signal processing. It contains two identical triode sections housed in a slim glass envelope. Because of its compact form and symmetrical design, it serves well in mixers, oscillators, and phase inverter circuits. Enthusiasts and engineers frequently choose it for VHF systems, test gear, and small signal amplification.

Balanced Gain and Strong Stability
Each triode delivers smooth, well-matched gain, making it perfect for push-pull applications. It also provides reliable performance across VHF frequencies while maintaining low internal capacitance. Moreover, Triotron’s solid construction helps reduce microphonics and distortion. In addition, the ECC91 ensures signal balance under continuous use. As a result, you get clean amplification and stable frequency handling in tight RF environments.

Versatile Format, Seamless Integration
The ECC91 features a 7-pin B7G base and a space-saving glass envelope. Therefore, it fits easily into compact layouts like tuner modules and vintage portable radios. Furthermore, it substitutes directly for 6J6 and CV4024 equivalents. Whether you’re restoring a mid-century receiver or prototyping a signal stage, this triode installs quickly and performs reliably.

Durable Quality from Triotron
Triotron is recognized for reliable European vacuum tubes that deliver consistent results. The ECC91 benefits from strong mechanical alignment, durable pins, and heat-resistant materials. Additionally, it supports stable output across temperature variations and extended operating hours. That’s why it remains trusted in both professional repairs and enthusiast projects.

Great for RF and Audio Builds
Whether you’re designing a VHF mixer or a small signal preamp, the Triotron ECC91 offers clarity, compact power, and dependable gain. Choose this tube for balanced signal paths, tight chassis compatibility, and vintage-correct performance in modern and legacy applications.
