Tube Amp Doctor TAD EL84-STR factory matched quartet (set of 4)
The all new TAD-EL84STR combines the best of both worlds. TAD chose the thickest glass option and most heavy construction like the Russian EL84M and sonically most promising cathode and plate option to meet and exceed the tonal quality of the EL84-Cz. Finally TAD added the gold grid wire to limit stray characteristics and to improve overall reliability. The result is the best EL84 currently produced.
