This small tube fits in the 6414 adapter and has more natural presentation with warmer and full bodied sound than my Raytheon 6414. It also has similar bass response incomparison to the 6414. This is the first time Mikhail tried this tube with his amp. |

RS also uses these tubes in his Raptor. I do like the ones I've found. |
