i just purchased my first tube amp, a fender blues deville reissue, and when certain notes/frequencies are played, i hear an awful rattling noise. nothing seems to be loose (visibly, anyway) and the tubes are less than a year old. any idea what could be causing this and possible fixes?

does it stop if you touch the tube?

Would that not just like, cause unnecessary burning of the skin?

preamp tubes don't get that hot, apparently.

Preamp tubes don't at all, I can touch one while it's on.

But be under no illusion that you can catch nth-degree burns off power tubes.

maybe somethings wrong with my amp then, because my preamp tubes are damn hot after a show

Preamp tubes would never really exceed a temperature like 50-60 degrees. That'd register as hot to a human but it's probably half or less of what a power tube can achieve.
