The TAD-EL84STR combines the best features of the renowned EL84-Cz and the EL84M. TAD, chose the thickest glass and heaviest construction available, similar to the Russian EL84M. This robust design is paired with the most promising cathode plate options to ensure that we meet and exceed the tonal quality of the EL84-Cz. Additionally, we incorporated gold grid wire to enhance overall reliability. The sound produced is very harmonious in the mid and treble frequencies, while not overpowering the bass. The result is the finest EL84 currently in production.

Due to its diameter of 22.5mm, the TAD EL84-STR does not fit into older Marshall DSL401 up to week 20 in 2014 and UK-made VOX AC15 TBX amplifiers. The only tube which fits these amps is the EL84-EI. (ordering number: NN471)
