The TAD 6V6GTB-STR BLACKPLATE™ offers a refined take on the classic 6V6 character. It delivers controlled, musical saturation, with warm mids and a natural, relaxed tonal profile. Its overall response strongly recalls the NOS models that marked the early days of valve amplification.
In comparative listening tests with 5E3 Deluxe and Fender 65 Deluxe Reverb amplifiers, this model matched the level of early-1960s RCA 6V6GT black-plate tubes. Its design benefits from optimal thermal stability, ensuring consistent operation and extended life.
This current production is made from the remaining original raw materials, and manufacturing resumed in early 2024. As with all TAD tubes, each unit is tested, selected and matched in Germany for rock-solid reliability.
It offers stable heat dissipation, detailed and precise reproduction, realistic rendering of vocals and a structure suited to complex, three-dimensional tones.
