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.
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.
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.
