so my center channel wasnt working, so i opened up the amp and found that it had a blown fuse on the center channel replaced the burnt fuse with a 250v 4amp slow blow like what is in there and then the two transistors for that half of that channel fried, the part # for the transistors is J162 then 6L3, i cant seem to find them anywhere, also does anybody have the schematics for this amp? also what else should i replace along with those transistors? any help is appreciated.
