sansui G4700

I have a g 4700 when powered up comes on but then blows the 5 amp fuse . think it must have a short. has anyone had this issue. I have down loaded the manual and have some experience with electronics. any help would be greatly appeciated

Re: sansui G4700

I would first check the audio power transistors (4 of them). If any of these are shorted it can cause driver and bias transistor failure (also resistors and other parts can fail).
