Probably the most rugged current production 12AX7. This tube is my first choice for cathode follower positions in guitar amps. You just can't kill these things.

These tubes are very close to the old GE version. I like switching pre-amp tubes on my tube amps and These work great. Also, I do trust Antique Electronic Sully. Good people.
