The JJ EL84 Output Pentode valve is used in famous amps such as the Fender Blues Jr., Vox AC15 and Vox AC30. It was also used in many record players in the 1960’s. In the USA the same valve is called the 6BQ5.
We also offer a 120 day from purchase warranty on the product ( excludes mechanical damage failure).
We test each valve /tube on our AVO valve testers. This ensures that we catch not only poor quality new valves but in the case of vintage valves we can detect and reject the worn ones. Note: Valves use high voltages and these voltages are dangerous. The amp can still retain these high voltages for some time even after being switched off. If you are not sure of fitting them , please seek the services of qualified personnel
