ok i've had it for about 3-4 years so i'm not even sure which one it is. i think its a 20-39 PCi. anyway we're moving stuff around and someone turns it off and unplugs both cables and moves it across the room. now plugging it back in all i get is loud buzzing. the fuse is intact. i'm sure it's cooked. i guess i'll have to get in touch with svs but shoot. now i dont have a sub for who knows how long.
