amp problems

[king of suede]

meh... i guess this was bound to come.. 2 years haveing it, buying it used,, blasting through it at practices and gig's and at home...

my amp to the best of my knowlage is dieing, but i don't want my hard earned teenage money to go to waste buy just throwing it out...

to the meat of things...:
when i play at even a resonable level, there are certain notes (usualy the open strings in any octave... E,A,D,G, y'know...), and then when i play loud, every note does this... my amp makes a sound that i guess you can compare to a bell ringing. when i put pressue onto the grill of the amp, it seems to soften it, but it's still there, and i'm convinced it's the speaker

the head i'm running through is a solid state/tube amp, so may it be the tubes dieing that's causeing this? for, i use more of the tube output then the solid state...

any help on this matter is greatly appriciated, and if you need any more explanation, i'd be glad to try to make it clearer

Is it like a harmonic bell or what?

IF its a tube/SS amp try using just one channel or the other and seeing if itmakes a difference.

Try different basses as well.

the bell ringing sound is due to the tube dying. change the tube and the problem should go away.
