Beware of Our Roughneck!

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 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 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. (ordering number: NN471)

Christoph Jaeger (5/5)

Great tube. Put a quad of these in my Budda Superdrive 30 and it tightened and opened up the whole amp. Great big tone with lots of definition and smooth harmonics!

By the way, on one of the tubes I broke a pin accidentally, and TAD sent a free and matched replacement, great service!
