The Classic Sound of the 1950s and 60s - Excellent Tone, Maximum Lifetime!

The TAD 6L6WGC-STR Redbase is the perfect choice for vintage tweed and blackface amps such as the 1960s Bassman, Twin, Showman or Super Reverb. The complex midrange and sweet heights are a class of its own. The TAD 6L6WGC-STR Redbase is recommended for classic tone with warm cleans and rich, sweet mids when pushed. Great for fat jazz or blues tones and our favorite in all open back combo amplifiers.

The TAD 6L6WGC-STR is a remake of the small bottle clear-top 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 a small bottle enclosure, clear top and side getter. The TAD 6L6GCM-STR and the TAD 6L6WGC-STR have our exclusive beefed up cathode coating, gold grid wire, double getter construction, no-noise filaments and 1.2mm thick heavy duty glass. This tube is only 84mm high (seated height without pins) and can replace 5881 or 6L6WGB tubes in most applications.

The TAD 6L6WGC-STR REDBASE™ is a glass envelope beam pentode with a plate dissipation rating of 30 Watts with convection cooling. It is intended for audio frequency power amplification service in either pentode, ultra-linear or triode connection and single ended or push-pull/parallel applications.

The TAD 6L6WGC-STR REDBASE™ is designed to be a direct replacement for any 6L6GC / 5881 or equivalent. Close manufacturing specification tolerances, gold grid wire, improved processing and final testing and QC at TAD in Germany provides enhanced reliability, superior sonic performance and grants overall consistency.

TAD 6L6WGC-STR REDBASE™ provides electrical and audio performance very similar to that of the original GE 6L6GC clear-top.

These sound great in my 1966 Bassman head and were very closely matched to within 1ma
Time will tell about long term reliability.
