The TAD EL84-CZ Premium Matched Quad gives most amps an extra powerful bass response. 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.
The EL84-CZ is the most powerful EL84 valve 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.
