i had my dad buy me this amp back in march at a guitar store. when i played it at the store, it worked fine, but ever since i picked it up at from my dads house, it doesnt work. for some reason, i think it might be the tubes, but who knows... i sure dont. it has four 12AT7's and one 12AU7 as well as 2 6V6's. it turns on, but makes no noise at all. thats about all i know, but if you need more info, let me know and ill tell you. please help me get this thing working again, its like my dream amp
