The TAD 6L6WGC-STR BLACKPLATE™ offers a compact take on the traditional small-format RCA 6L6 design. It reproduces the warm low-mids and smooth highs characteristic of the original 1950s and 1960s versions, while retaining a controlled response both clean and overdriven. The tonal profile of this tube makes it perfectly suited to classic tweed and blackface amplifiers.
This model follows the construction principles of vintage RCA 6L6GC and 5881 tubes, with black plate anodes, a side-getter structure and carefully selected materials from original stock. Production resumed in early 2025 and each tube is tested and selected to guarantee consistent behaviour. Its dimensions and operating characteristics allow it to replace 6L6WGB and 5881 tubes in amplifiers requiring a more compact format.
It features a black plate system, a gold grid wire, a dual-getter design, low-noise filaments, a robust glass envelope and Premium selection and matching by TAD in Germany.
