The JJ ECC803S is a long plate version of the ECC83S and is fully ECC83/12AX7 compatible. The long plate imparts extra cooling, improving service life. It also enhances bass and mid range compared to the standard ECC83S.

Note that long plate valves are more susceptible to microphonics than short plate valves, so add a damper ring when installing in a combo amp. This is not an issue with amp heads.

We test each JJ ECC803S at real amp voltages on our suite of vintage, modern, and custom-built valve testers for performance, noise, and microphonics.

Made in Slovakia.

★ Premium Valve Testing

Our Premium Tested Valves are the only valves in the world tested for noise, longevity, and real-world performance. We run them at real amp voltages, sound-check for noise and microphonics, and carefully match output sets to deliver maximum reliability and tone. You can't buy a better valve. Each one comes backed by our industry-leading 180-day warranty. Learn more about what makes these the world’s best valves.

★ Shipping Info

Shipments within the UK come by Royal Mail with 24 hour tracking (no deliveries on Sundays). We also offer international shipping. All orders securely packaged.

★ Safety

Please make sure your amp's bias is set correctly. If not, you could hamper your tone and even limit the life of the output valves. Also note that valve amps can retain high voltages even after being switched off. If you are not sure of fitting your valves, please seek the services of qualified personnel.
