sometimes they'll glow purple. I think it was due to some trace gases inside the tubes.

I don't think it's a problem unless the entire tube starts glowing red.


actually, according to the eurotubes faq:
A blue or purple glow that pulses under load is normal. A strong purple glow that shows up when a tube is not under load at idle means the tube is "gassy" and is on it?s way out. This is usually caused by improper vacuum and when under lead shows a very intense purple glow.

Well, my guitar teacher tells me it isnt good that your tubes glow blue or purple. It means that the tubes lost their vaccum and needs to be replaced.

^ I agree with that. Most tubes glow orange. If you tap on the tube when your amp is on, does it make a noise?

Yea try that, turn it up all the way then tap the top of the amp.

are you talking about pre amp or power amp tubes? and are they SUPPOSED to glow orange a little bit? or not at all?

They are supposed to glow orange, when u hit a chord or something, the power tubes glow brighter.

Tapping on the top of the amp probably won't do anything. Plus if he has reverb, it's more likely to be the reverb tank than the tube. You need to tap the tube itself, either with your fingernail or with the eraser-end of a pencil.
