Presented is a premium vintage Tungsram ECC82 (12AU7), a hallmark of German engineering. This unit features the coveted Diamond Bottom mark and a large ring getter. Tungsram valves are highly regarded for their robust construction and analytical yet musical sound signature, making them a preferred choice for studio gear and Hi-Fi systems.
This unit has been precision tested on the Amplitrex AT1000 digital laboratory tester. The results follow the Percentage Method against original factory design-center specifications (Ip = 10.5 mA / Gm = 2200 µMhos). Testing with balanced mutual conductance across both sections, this tube is in excellent working condition.
