Question about Audio Players & Recorders

1 Answer

I have a digitor subwoofer (A3111) and it looks like the fuse is blown. Looks like it needs a "F1AL 250V" fuse - but when I looked for one in the shops, I couldnt find it. Do they still exist? or am i not looking hard enough... or is there an alternative?

Firstly, the fuse is just a slow blow 1 Amp short style. You should be able to get an equivalent at any electronics parts supplier (a 1.25-1.5 Amp will do as long as it is the correct physical size).

Secondly, the cause of it blowing the mains fuse is probably a short in the primary winding of the Toroidal transformer. I have now replaced the transformer in mine twice over about 4 years.

If you cannot get the original Toroidal transformer (with the correct connectors) use a 50 or 80VA 12+12V Toroidal Transformer and connect the secondary windings in series. You should be able to get one for AU$30 to AU$40.

I need to find a fuse for my jbl sub 160 subwoofer.


Those are pretty common. I'd pull the old one just to make sure the new one looks like it and be SURE the new one is a "Type T" or Slo-Blo.
Google "30mm 3.15A 250v slo blo fuse" and you will find them at Mouser, DigiKey, even Amazon. Better still--if you have a local electronic parts store, go there.

Klh subwoofer keeps blowing it's fuse.


Most likely the amp in the sub has blown. It will need repair or replacement. I'd take it to an expert in repairing amps, it's not a job for you unless you're experienced in troubleshooting these things.

KLH ASW8 Powered subwoofer keeps blowing 3A-250V fuses


The transistors at the output stage of the sub amplifier circuit might be shorted so each time you power on, the circuit draws a very high amount of current which causes the fuse to blow. It's definitely a problem with the circuit so using a higher current rated fuse would probably just result in damaging the amp even more. You should ask a qualified electronics technician to take a look at it. I hope you can fix it.

A few days ago the subwoofer stopped working. Yesterday I turned the system on and it wouldn't work at all. I discovered the fuse had blown. I replaced the fuse, couldn't find a slow blow fuse so had to...


Try removing the wires to the subwoofer and then hook a "aa" battery to it and see if it makes a pop sound..this will tell you if speker is ok...if it is then I think the amplifier sectionj for the sub is what is blowing the fuses...you are probably right..it looks like it's a 1 A fuse...but if it's blowing right away..it may be circuitry related

PS8 Subwoofer started buzzing non-stop


with nothing connected and the sub turned on....Most subs buzz when the circuitry starts to fatigue. The last time I heard this ..the repair ended up being one of the two fat capacitors inside the sub. I have a means of testing this,,you may not. I am a repair shop with a bit of experience in component level board repair.

Fuse T1.6L250V


The fuse which you have used is of correct rating 250v/5A, the switching regulator of the SMPS primary section is faulty, so the fuse blows of continously
