This product is currently out of stock and will be placed on backorder. This product has substitutes available! Check them out.
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
