From our review: "This tube has the deepest bass, the highest highs and solid mids. In short, they sound a lot like a premium 6V6. No smooth creamy distortion here but tons of rock and roll crunch. If your bored with your normal EL84 tone these are definitely tubes to consider."

TAD says the following about their new EL84 power tube:

"The all new TAD EL84-STR tube combines the best of both worlds. We chose the thickest glass option and heaviest construction like the Russian EL84M tube and sonically most promising cathode and plate option to meet and exceed the tonal quality of the JJ/Tesla EL84 tube. Finally we added the gold grid wire to limit stray characteristics and to improve overall reliability. The result is the best EL84 tube currently produced. No compromise!"

Note: These tubes have a slightly larger diameter than other EL84 tubes so they can not be installed into some '90's era Marshall DSL201 or DSL401 amplifiers, some '90's era reissue Vox AC15 amps, and Bad Cat amps.

Lacking Bass? Try These Out!


I purchased these tubes for a brand new Orange Rocker 15 combo. With the 10 inch speaker that comes stock and the JJ EL84 tubes, the amp lacks a lot bass, even with the bass knob cranked. I was looking for a tube that would add bottom end but also clarity as the JJ tubes and the nature of the amp have it voiced quite dark and a little muddy. The tubes definitely added the bass I was looking, again, it could use more but that’s my preference, just the nature of the amp. I also changed the stock JJ 12ax7s for some Tungsol 12ax7s but kept the stock Ruby 12ax7 in the PI. I am very happy with the sound of the amp now, the volume knob has a much better sweep, much more useable
