According to our tube substitution handbook, the 5U4GB is not a replacement for the 5U4GE.

No, the only time you might need to rebias is when you are replacing power tubes.

This is something we would not recommend as the 5U4GB runs at a higher filament current and you run the risk of overheating your transformer and damaging your amp.

Very nice sounding tube, sorta' luscious, sweet, and full range. My NOS favorite 5U4GB used to be a Tung Sol, but this out-performs NOS tubes in my two stage direct coupled amps. I LOVE what a DIRECTLY heated rectifier tube does. I have been told the Electro Harmonix 5U4GB ( handled by Antique Electronic, and reasonably priced !! ) has a little more " snap " to it, dynamically, but I was also told it takes 200 Hours of playing to break-in to full bloom. This JJ takes maybe only 15 hours to break in - in my DC SET amp circuits. Amazing, two modern tubes that each beat the old timers.
