One Matched pair of JJ Electronic EL84's. The JJ EL84 tubes have achieved status in the industry as the best new production EL84 available, rivaling and surpassing many NOS tubes. It's warm, powerful, and very smooth with a sweet chime, a remarkably defined mid and tight punchy low end. A superb replacement in any EL84 combo amp or head.

At Eurotubes there is no such thing as platinum matching or an upcharge for "closer matching" . All power tubes are matched within one milliamp period.

After a 24 hour burn-in all power tubes are tested for noise and matched at multiple operating points for plate current ( ± one milliamp) and transconductance. This is done on our custom made Kamna Matcher. The voltage is regulated to within a tenth of a volt and the high DC voltage is applied to all tubes simultaneously. The Kamna Matcher features individual readouts for each socket and each socket is fully active during the duration of the matching process which includes testing for current, transconductance and individual audio tests.

The video below shows both our preamp tube testing and power tube matching procedures here at Eurotubes which are second to none. We may not be the cheapest, but we are arguably the best.
