I own a Peavey 6505 +112 combo amplifier. A while back, I turn it on it and get this static that increasingly gets louder now. So I'm guessing my tubes need replaced. (Unless someone else thinks something else is going on.)

Anyways, this will be a first for me, so I figured I'd ask around here to see what others might suggest. I am a "metalcore" fan, so I do want to stick with that sound/tone, if that's even a factor. (Metalcore get's bashed on this site a bit, please troll elsewhere.)

I did come across thetubestore.com, and they have some premade packages, and that's what I'm kinda leaning to... any input on the site or other suggestions is welcomed. Thanks!
New tubes.
