So my amp plays fine, but whenever i turn up the master there is a slight chiming. Almost like somebody is ringing sleigh bells when im playing. I got told it could be a pre amp tube, so i did the tube test with a pencil and sure enough when i tapped this tube it made an almost weird noise. So i've just replaced the tube, but it still happens.

anybody give me an insight as to what this problem is?

Start with a shield or an O-ring on the tube to keep it from ringing while you play.

So the noise i'm hearing is the tube itself rattling? And an O-ring around the tube will sort the problem?

Probably, and probably. A silicon O-ring is fifty cents at the hardware store, so it's a good place to start.
