Vacuum Tube - EL84S-STR Blackplate, TAD, Premium Selected
The Tube Amp Doctor Blackplate series offers the highest tube performance due to the stable heat dissipation of the black anode. This results in an increased tube-life and tones that rival the classic NOS tubes. The EL84S-STR offers rich sounding breakup with its warm and pleasant mid tones. These tubes are matched for both plate current and transconductance. The EL84S-STR pass all of the tests of the TAD Premium Selection process. The TAD EL84S-STR can be used in any standard EL84, 6BQ5, 6P14P, or N709 position.
Note: The TAD EL84S-STR has a 22.5mm diameter and does not fit into older Marshall DSL401 and UK made VOX AC15 TBX amplifiers. Please check your amp before ordering.
