nope :cry: i am trying to swap the power tubes out and see what happens
 
GEt spare fuses and run the amp without the powertubes first.
If the mains survives this, put new powerubes into the amp and rebias.
Check tube fuses on the back.

it sucks. i have no idea where to go and who to ask about it.do you have any idea?
i bought it online back in 2007
 
Could be something simple like a diode or the hum trimmer. Wait until Peter sees this, he will recommend somebody.
 
ciao Frantic, non disperare, sicuramente è roba da poco ;)
prima di portarla al tecnico sostituisci tutti i fusibili possibili, l'importante è che siano dello stesso amperaggio - voltaggio.

facci sapere!
