J'utilise ces tube sur un Jadis DA88S et je préfère vous prévenir que le rodage est très long.
Prévoyez minimum 100 heures avant d'avoir une idée et 500 heures pour un rodage total.
Très bon tube si vous avez la patience d'attendre.

Power tubes high quality (Matched Quad)
The Tung-Sol KT120 has a 60W dissipation tray, making it the most powerful tube in the 6550/KT88/KT90 family. A pair of these tubes in push-pull configuration can deliver between 150 and 200W. When used with existing 6550 / KT88 / KT90 circuit parameters, the KT120 becomes overload proof, delivering peak power with extreme reliability and very long life. Moreover, by taking advantage of the ability of these tubes to handle high currents, it is quite possible to design a unique, powerful and stable amplifier.
The Tung-Sol brand has long been known for the high quality of its tubes but also for their incredible timbre. Manufacturing quality that lasts, even on these new models. Thus, Tung-Sol tubes reflect the best of the brand's vintage manufacturing, with unmatched sound and reliability.
These tubes are delivered by 4 and are matched by the brand in order to obtain the closest values and therefore the best possible performance. Ideal for perfect assembly.
