The TELEFUNKEN 6L6GC-TK has tight and defined lows, transparent mids and a shimmering high end. When installed into your amplifier, these octal power tubes offer a focused bite with well-defined articulation.

The 6L6 was developed by RCA in 1936 as the first power tetrode, an alternative to the high output pentode designs already under patent by Philips. The modern version, the 6L6GC, dominates the guitar amplifier market no different than the earlier versions that have been found in Fender amplifiers since the 1940's.

The 6L6 is most associated with American sounding amplifiers. In comparison to the EL34 and EL84, the 6L6 tends to not break up as quickly. With it's top-end sparkle and clean headroom, their is a reason the 6L6 has had one of the longest active lifetimes of any electronic component.
