The TAD 6L6GC-STR BLACKPLATE™ delivers a balanced reproduction of the traditional sound of the famous 6L6. The bass is powerful and deep, while the highs remain clear and precise without being intrusive. This tube offers rock-solid reliability, from clean set-ups to high-gain environments.
This model combines the proven robustness of Philips/Sylvania STR tubes (also listed as MESA 6L6GC-STR415) with the black plate architecture characteristic of classic RCA 6L6GC tubes. The result is a stable tube with plenty of dynamic headroom, smooth highs and a consistent bass response, ideal for clean amplifiers as well as multi-channel systems requiring a wide bandwidth.
It features a black plate system, a gold grid wire, dual getter construction, low-noise filaments and a high-strength glass envelope.
