The all new TAD-EL84-STR Redbase brings together the best of both - the famous EL84-Cz and the EL84M. We opted for the thickest glass possible and the heaviest construction available, just like the Russian EL84M, and combined these features with the sonically most promising cathode plate options, in order to meet and exceed the tonal quality of the EL84-Cz especially with regard to its linearity over the entire frequency range. Finally we added the gold grid wire in order to improve overall reliability. The sound can be described as very harmonic in the middle and treble frequencies, without adding too much power to the bass. The result is the best EL84 in current production.

Note: Due to its diameter of 22.5mm, the TAD EL84-STR does not fit into older Marshall DSL401 made till week #20 in 2014 and the UK made VOX AC15 TBX amplifiers from the same time period. Later versions of these amplifiers have been updated to accept 22.5mm diameter tubes with no problem.
