Description
The Tung-Sol EF806 / EF86 is a reissue of the classic low-noise pentode, one of the quietest valve types available for phono stage, microphone preamplifier, and sensitive signal amplification applications. The EF806 designation indicates a selected, premium-grade version of the EF86 produced to tighter noise specifications.
The EF86 was used in some of the finest vintage phono stages and is closely associated with early Vox amplifier designs, appearing in the AC15 and early AC30 as the input valve. Tung-Sol’s modern reissue provides a reliable option for enthusiasts and amp builders seeking this specific valve type.
Note: EF86 valves can be microphonic — proper installation and damping is recommended. Noval base. Supplied as a single valve.
