Ps12 sub woofer. How do I replace the fuse?


There is a photo of the amp board here:

You need to remove the plate amp from the speaker (be sure it's unplugged!) and you'll see the fuse. Replace with exactly the same thing--don't go up in amperage. BUT... if it blew a fuse something is wrong. Those amps do have a tendency to over-heat but if the new fuse blows you should have the amp serviced. Or junk it.

Hi, we moved the sub woofer from its original position and now it keeps blowing fuses. I would like to repair the sub woofer, as it works well and is quite new. I live on the south coast of NSW...


Where was it sitting before it was moved? Did it have it have more ventilation and keep cooler? This sub has a powerful amplifier in it. If it got moved to an area that restricts air circulation around the sub more it is possibly overheating and causing fuses to blow. Put a fan on it and make sure it is on a hard surface or up off the carpet at least to keep the bottom side cool as well. Also when one moves a speaker it's often to put it into a more convenient area to be able to turn it up louder with less disturbance to others. This will draw more power and create more heat within the amplifier than it's previous location. If this is so keep it as cool as you can and turn it down every so often to give the amp a rest. The key here is to keep it cool as you can. One thing you never want to do is put a higher rated fuse in than the unit is rated for. Always use factory recommend fuse rating.

Ps-1200-A sub woofer will not power up


Probably a blown fuse. If there's not one on the face of the amp, pull the amp and check for one next to the power cable.

Unit blew the internal fuse. SONY SA-WMS367 SUB-WOOFER


Bad output IC or voltage rectifier are the most likely at fault.

Fuse blows


Both 3 or 4 amp slow blow fuses are suitable replacements for the 3.125 amp subwoofer fuse.

It could be that the subwoofer is blowing the fuse because the one you installed was not slow blow.

But, more likely is the subwoofer has a short in the power supply which is causing the fuse to blow.

No LED light on PSB Alpha Subzero-i and keeps blowing fuses.


Others have had similar problems with the amp on this model. There is probably a circuit design error which causes some components to blow and as far as I've read, fixing it (or replacing the fuse) won't make the problem go away for long. Try contacting PSB or the retailer.

Sub woofer keeps blowing fuses


NO dont try a 3 amp fuse.It is made to BLOW if there is a problem. That sub is not worth fixing, JUNK it. There are a lot of problems with it. Such as heating up and melting the board witch could cause fires. Thats what happened to mine. Like I said JUNK it and buy a different one.
