Vacuum Tube - 6L6WGC, Tube Amp Doctor
GE-Style 6L6GC with a short bottle and black plate.
The Classic Sound of the 1950s and 60s - Excellent Tone, 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 TAD 6L6WGC-STR is our recommendation for classic tone with warm cleans and rich, sweet mids when pushed. Great for fat jazz or blues tones.
The TAD 6L6WGC-STR 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 6L6GC-STR and the TAD 6L6WGC-STR have our exclusive black-plate desings, 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.
