The TAD 6L6WGC-STR Blackplate is a remake of the small bottle GE6L6GC and has the same warm lower midrange and silky top end as the classic GE versions of the 1950s and 60s. Like the historic RCA 5881, this tube features exclusive blackplate anodes and a side getter. The TAD 6L6WGC-STR Blackplate has exclusive blackplate design, gold grid wire, double getter construction, no-noise filaments and 1.2mm thick heavy duty glass. This tube is only 80mm high (without pins) and can replace 5881 or 6L6WGB tubes. The TAD 6L6WGC-STR Blackplate features the classic sound of the 1950s and 60s, providing excellent tone and maximum lifetime. The perfect choice for vintage tweed and blackface amps such as the 1960 Bassman, Twin, Showman or Super Reverb. The complex midrange and sweet heights are a class of its own. The 6L6WGC-STR Blackplate is TAD’s recommendation for classic tone with warm cleans and rich, sweet mids when pushed. Great for fat jazz or blues tones. The TAD 6L6WGC-STR Blackplate is a glass envelope beam power pentode with a plate dissipation rating of 30W with convection cooling. It is intended for audio frequency power amplification service in either pentode, ultralinear or triode connection and single or push-pull/parallel applications. The TAD 6L6WGC-STR Blackplate has an indirectly-heated oxide cathode, which may be DC operated for the absolute best hum/noise performance.
