INFINITY BASSLINK X BLOWS FUSES

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.

    sorry for restoring this thread but i'm currently running through the same issue and i just saw that transistors D105 and D106 were shorted. After taking them out, i see that they are fine but the circuit in which they are is shorted. I cant trace which transistor is causing the shortage, do you guys have any idea?

My basslink worked great, son blew fuse, replaced, now sounds lik


If the speaker has been overdriven, it may have damaged the cone surround or damaged the speaker coil, causing it to 'rub' inside the magnet. To check for rubbing, you need to move the speaker cone backwards and forwards by hand and listen where the speaker coil/cone goes into the magnet. It should be silent if ok. If you can heara rubbing or grating noise, then the speaker is damaged. If the output driver on the amp is damaged it can give a distorted sound, which could easily happen if it tries to provide too much current.

2nd Basslink, still no power-on. Please help


this is in response to the post below:

I just bot a basslink t and i wired it up and nothing it just keeps blowing the fues in the unit i got mine on ebay2.gif so i dont know if i can use the warranty dose anybody have an ida for me- britter623

I got a used basslink about a month ago and had the exact same prob kept blowing fuses...found out that the voice coil had blown on the infinity...so I had a brand new dvc polk 10 sittin in the closet, I swapped them out, put the polk in the place of the infinity sub, however, the magnet is much larger, hence, dual voice coil, it would rattle sooo much from the passive radiator against the magnet, also could not turn the gain up at all due to the rattle. I got the bright idea to build a "custom fiberglas enclosure for the polk and incorporate the infinity's parts(amp/control) I finished the box finally last night and hooked it up this morning, no power, no lights, no nothing! s@#%, F&@%! ANyone had a prob w/the amp not having the lights turn on, no power??? Hope that helps about your fuse blowing issue.

Amp keeps blowing fuse


I have this same problem. You have blown the internal amp. I have had 2 of these do the same thing. There is nothing you can do but report it to infinity and try to get the unit replaced.
