Our Fender Blues Junior valve kit uses exactly the same valves as originally fitted to these classic amps. The kit contains three Sovtek 12AX7WAs and two matched Sovtek EL84s. Fender designed the Blues Jr to use medium gain Soviet 12AX7WA valves.
We carefully match the EL84 output valves and specially select a balanced 12AX7WA for the phase splitter. You will receive a test certificate showing the matching info.
Sovtek manufactures their valves in the world’s largest remaining valve factory. Many amp manufacturers favour Sovtek valves for their superb tone and reliability. The factory tests their valves under US Dept of Defense Mil Std 133 Revision D. We then retest each valve here at VTGA on our suite of AVO and custom-built testers. You can’t buy a better tested or more reliable valve.
We also have a Fender Blues Jr Kit with EL84Ms.
We offer EHX, JJ Electronic, Genalex, Sovtek and Tung Sol valves and can assemble bespoke kits for your amp.
Your valves come with a 180 day warranty.
