TAD EL84-Cz TAD PREMIUM Matched Quartet RT274

The TAD EL84-CZ is the muscle man and roughneck among the EL84 models. It gives most amps
an extra powerful bass response. Be careful with amps that already have a fat bass and make
sure their speaker can handle the increased bottom end as it might become too much. The EL84-Cz
is the most powerful EL84 tube we have ever heard. Big tone and very dynamic. Our recommendation, if a
powerful tone is what you are looking for.
d= 22.5mm

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. (order number: NN471)
