Designed for audio and signal amplification tasks where stable, lownoise performance is required. Standard 9pin Noval footprint lets you install the tubes into existing sockets without modification. Glass envelope and metal electrode construction for reliable electrical contact and visible condition inspection. Supplied as a matched pair to simplify channel replacement and help maintain balanced performance in stereo systems. What this product does and why you need it Function: dual triode amplifier tube suitable for preamplifier stages, driver stages, and other low to medium power amplification roles. Problem solved: replaces worn or noisy tubes to restore clarity, gain, and consistent operation in vintage and modern tube equipment. Standout points: broad compatibility with multiple equivalent tube models and a standard form factor for easy, dropin replacement. Important attributes Compatibility: explicitly listed as replacement for ECC85, 6H1n, 6AQ8, 6N1M, and 6N1Q. Size and fit: standard 9pin Noval base for direct mounting into compatible sockets. Material: glass exterior with metal internals and precision pins for secure electrical connections. Performance: intended to provide stable amplification with attention to consistent characteristics between the two tubes in the set. Practical applications Restore a vintage FM tuner or radio that uses ECC85 type dual triodes as frequency or audio amplifier stages. preamp tubes in stereo hifi systems to recover channel balance and reduce hiss or distortion. Use in DIY audio projects or tubebased signal processors where a compact dual triode with a 9pin base is required. Notes on installation and handling Install and remove tubes only when equipment is powered down and fully cooled. Ensure correct orientation in the socket and consult your equipment manual for any bias or adjustment procedures after replacement. Allow a short warmup period after powering up for stable operating characteristics.
