Can I use a 5u4 rectifier tube on my SE84UFO2.1 (Read 714 times)

beaufleuve Verified Member Posts: 8	Can I use a 5u4 rectifier tube on my SE84UFO2.1 10/23/24 at 17:12:21 hey, I have a newish custom unit that's not playing. I want to switch out the 5u3 rectifier tube to see if it's bad. I have a zen preamp that uses the 5u4, so thought of trying that. good idea? thanks
