TAD EL84-CZ Premium Matched Single

Be careful with amps that do already have a fat bass and make sure their speaker can handle the increased bottom end as it might become too much. Due to its diameter of 22.5mm, the TAD EL84-Cz does not fit into older Marshall DSL401 and UK made VOX AC15 TBX amplifiers. The only tube which fits these amps is the EL84-EI. (ordering number: NN471). Our recommendation, if a powerful tone is what you are looking for. All power tubes labeled Premium Selected have passed the following tests: - Plate Current (PC) and Amplification (TC) - Low Noise Test - Microphonic Test - Sonic Tests - Shock Tests - Listening Tests - Shorts & Leakage Tests
