In Reply to: What's the difference between the 5U4, 5U4G, 5U4GA, and 5U4GB tubes? posted by PeterCapo on January 10, 2001 at 14:18:28:
All the same tube electrically.No such thing as a 5U4. The G means glass, the early version is the 5U4G which is ST shaped. Sonically (depending on brand - Tungsol is best, KenRad, Raytheon also very good, RCA & Sylvania a bit less but still good) the best but sometimes had a reputation for not being reliable.
5U4GB is the straight bottle version, GE made one called 5U4GA which is the same. More rugged & reliable. Best sounding by far to me is the Tungsol. Others are not nearly as good, except the Sylvania 5931 which is a very rugged military variant.
