Tubes Asylum Questions about tubes and gear that glows. FAQ |

I have two GE 6SN7GTB tubes with filaments on top, green lettering on glass. What are they (year of manufacture and overall rating?) In a particular amp, they surpassed the Sylvania VT-231 (much warmer and lifelike, more relaxed, but more colored), while the Sylvanias are good when used in another amp.I will appreciate all comments and opinions.
