Vacuum Tube - 6L6, Electro-Harmonix
Superior power Beam tetrode with large plate dimensions and improved grid structure for increased power handling capabilities. Excellent tone and performance compared to most other 6L6 or KT66 types.
- Modeled after the vintage RCA 6L6GC "blackplate"
- Mica spacers with metal springs eliminate tube rattle and microphonics
- 5881/KT66 equivalent
Matched versions of this tube use Apex Matching
RoHS Compliant
