Electro-Harmonix 2A3

Power Tube Platinum Matched Gold Plated Grid (Matched Pair)

Electro-Harmonix 2A3 Tube de Puissance Appairage Platinum Grille plaquée Or (Paire appairée)

The high quality Electro-Harmonix 2A3 power tubes are tubes with direct triode heating by oxide cathode. They are ideal for a low frequency power amplifier in the amplifier output stage. The gold grid of these tubes provides exceptional bias stability. At the base of the tube are 4 gold plated pins on ceramic support.

The two tubes are perfectly matched to obtain exactly the same current, maximizing their performance. The Electro-Harmonix "Platinum" pairing consists of a 24-hour burn-in period followed by a measurement in milliamps of the bias current to ensure the perfection of the pairing.

Lampes fantastiques.
Bonjour, je viens de recevoir les tubes EH 2A3 et je les ai déjà montés sur mon ampli, le son est déjà fantastique, sans préchauffage, supérieur en richesse harmonique et en détail par rapport aux Golden Dragon en ma possession.
Je tiens à vous remercier pour le service rapide et courtois et j'ai hâte de faire d'autres achats dans votre boutique.
Joyeuses Pâques et salutations d'Italie!
