Telefunken 6L6GC-TK overview
- 1Description
The Telefunken 6L6GC-TK Black Diamond Series Vacuum Tube is ideal for use in guitar and bass amplifiers and hi-fi equipment in homes, studios, and live stage applications. For personal enjoyment, live performance, or commercial recording, it grants a clear midrange and sparkly highs. Slightly larger than an EL34, this 6L6GC octal power tube delivers bite, definition, and plenty of headroom.
- Inspired by the 6L6, which was developed by RCA in 1936 as the first power tetrode
- Strongly associated with the sound of American amplifiers
- Great for instrument amplifiers and hi-fi equipment
- Tight and defined lows, transparent midrange, and shimmering highs
- Focused bite with defined articulation
- In comparison to the EL34 and EL84, the 6L6GC is characterized by higher headroom before breaking up
- Each tube is meticulously measured for all critical parameters of performance including transconductance, gain, noise, and microphonics
- Tubes are selected by hand, rigorously tested, subjected to an extended burn-in period for stability, and remeasured before final packing
