SOURCE: 6.3a slow-blow 125v fuse

It will work, the amp rating is most important, 125v / 250v does
not matter.......note: if you blow the fuse again, the TV will
need service.................T.

SOURCE: AR1 Subwoofer Keeps Blowing the 5 Amp Fuse

Well, so far so good. I reinstalled the newly repaired amp and fired it up and so far, so good. Ran it through about an hour of fairly intense break-in tracks and then ran it through about 2 dozen power up and down cycles to try to get it to fail (better now than a month from now and have to fight them on backing it up).

SOURCE: PC power supply fuse - T6.3h 250v engraved on end

T = time delay (slow blow)
6.3A = 6.3 Amperes maximum load
H = HRC - high rupture current (as you specified a ceramic fuse)
250V = 250V AC rated

other letters you may see
FF = ultra fast blow
F = fast blow
M = medium blow
TT = very slow blow
L = low blow current
H = high blow current (glass package)
S = sand filled

SOURCE: Klipsch ksw subwoofer wont power on

The problem is Klipsch's problem, and they don't seem to want to face it. My 10" subwoofer blows the fuse before the power light can even come on. It's obvious that the fuse is not strong enough, but there is a delicate area between the fuse and the power supply. Too many amps on a fuse may keep it from blowing, but it may cook the power supply. Kipsch needs to fix this, tell us how to fix it, or replace it...at their expense. This should NOT be happening. Otherwise a great speaker....when it works.

SOURCE: subwoofer eating fuses.

Check the circiut board for any blown capacitors. Sometimes it's that simple as replacing a capacitor. But then again, what is causing the capacitor to blow??/ Hope this helps.

Blew a fuse what kind dose it take is it a slow blow fuse or fast blow one,i took out the old fuse and it reads le.3a/250v is it a 3a or .3a


It is a 3A/250V fuse, also known as a 6A/125V fuse.

Power amps generally have slow blow fuses.

The required fuse is 1.6 A / 125V an is blown, I wen to radio shack and bought a 1.6A/250V and it has blown 2 already, what can I do or check to fix it? This is a Sony Sub-woofer model sa-wmsp1.


Hi,
If power transformer T1 got shorted or its output voltage got shorted for some reason, fuse will blow in Sony SA-WMSP1 active subwoofer.
Check power transformer, D401 bridge rectifiers and IC301 power amplifier out chip. Any of them is bad.
Let me know if you have additional question.
Thanks.

Jamo i300 dies after powercut


If its out of warranty you might as well open it up , and if your lucky it might only be a fuse to replace , if it is fused inside it will probably have blown before it could do any damage to circiuts . hope this helps

No power in the system


Did you have to replace the fuse? Was it opened? Sometimes there is a THERMOfuse INSIDE the transformer [xfmr].Before it blows because of too much heat ,it may blow the 2a 250v external fuse.You must check the power supply [the circut attached to the fuse] input should be 120 a/c in and around [+] or [-] 12 v thru 15 v DC output. Look for filter capacitors & resistors that look like tiny cement blocks(they are thermo type fuse resistors) BE KILEFULL !!! (CAREFUL) the voltages are low but the current could be high. Could stop your heart!!
