Tetrode Amplification Tubes (Matched Quad)

Electro Harmonix 6CA7 Tubes d'Amplification (Set x4 Appairés)

The Electro Harmonix 6CA7 amplifier tubes are classic tetrodes in Big Bottle format. They are designed to adapt to amplifiers with high gain while providing precision and sound richness to restore the integrity of the original audio signal. Their design allows them to saturate less quickly than many other tubes, thus preserving beautiful sound clarity, even at high volume. 6CA7 tubes are also compatible with EL34 models, for example for replacement.

Matched quad

These Electro Harmonix 6CA7 tubes are delivered by 4 and are matched by the brand. This process allows to obtain almost identical values for each tube in order to improve its performance. Ideal for perfect assembly.
