The JJ EF806S valve is a brand new replacement for the famous EF86 from the 1950s and ’60s. JJ Electronic designed the EF806S as a low noise, low microphonics version of the original EF86. The US number for the EF806S Audio Pentode is 6291.
This high gain pentode produces a unique sound when overdriven. Vox amps used the original EF86 to help get their mojo. The sound from an overdriven EF86 has to be heard to be believed.
You can now save yourself a lot of money on buying NOS EF86 valves and grab a brand new JJ version.
We test each valve at real amp voltages on our suite of vintage, modern, and custom-built valve testers.
