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.

Replacing tube constellation on a stereo amplifier - needed a dual rectifier. The plates in this one are much longer that the original 5Y3.
