Question about Infinity BASSLINK Car Subwoofer
I am a technician but have no schematic OR recent experience. My Basslink X blew the 20 amp fuse. It's own fuse. I found that one of the switching xistors ahead of the torrid transformer was dead shorted. I replaced both of them with exact replacements. I powered up the unit but limited the current to under 10 amps. When the trigger lead is on it would have blown the fuse. With the lead off it does not blow the fuse after the transistors were replaced. Is there anything that is a "frequent problem" with these units? Note: the bridge rectifiers just after the torrid are fine.
What probably happened was both of the final audio output transistors shorted. This caused a higher than normal drain on the switching transistors on the primary side of the torrid power transformer causing one to short and then blowing the fuse. I replaced both switching transistors and ramped up the current to about 5 amps. I could see the power supply was not working but there was still a short. I traced the short to both audio output transistors. Replaced them and unit is like new. After I found a service manual on this item it was a breeze to find the problem.
