Replacing Tubes

[engulfedinlies]

I got my 3 Channel Dual Rectifier about 2 months ago, and I got it used from a guy who said he had just replaced the tubes. I noticed that one of my power tubes (5U4GB) is not glowing like the rest of the tubes when I turn it on. I was going to just replace that tube by itself, because I'm figuring it must be blown. Should I replace all of the tubes just to be safe or just that one?

The 5U4GB is your rectifier tube, not a power tube. It will always appear to be different :roll: If it wasn't working properly, you wouldn't hear any output from your amp (well, I guess you might if you were in a solid state rectifier mode).

Relax and enjoy!
