Can I run this in my Fender 68 custom Deluxe Reverb re-issue, or do I have to get a 5y3-g or a 5r4gb? I want to soften the attack some.
Asked by Anonymous on October 26th, 2017.
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.

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