Re: Fuse

Radio Shack or an AutoParts store like Napa.

Make sure the replacement has the exact same rating as the original.

I have a jbl 515 eon no power every thing is dead the fuse is ok

If you can watch the fuse kind of twitch. Most likely you have somthing shorted in your output amps. ( the ones on the heatsink underneath PCB) you'll probolly need a tech for this one to change out the transistors. Still under warranty?

There is power coming from my outlet, but the speaker is not turning on. what is the first step in I should take, and then the steps there after?

Well there is an internal fuse in this system. Some companies locate this within the main power transformer as a thermal device. It may be as large as 4 amps. However you may have a hard time removing this fuse.Not saying it can't be done but the transformer has to be carefully disassembled.You may also jump this device but you should always install a fuse of the same value for protection. So now this fuse may have blown due to transistor failure. Look for burned resistors around the finals to give you an idea of how much damage you may have. One thing is for sure if a fuse goes it is because of a severe load and should be dealt with carefully. THE GREAT OZ.

Hello........ looking for a schematic for Bose 501 series 3 speakers. I need to replace the fuse in line with the tweeters.... its blown & does not have a value on it (unmarked, quick blow, twin lead,...

Did you find a solution? Dunno if it's much help, but I just today picked up some 501s - Series I I think - ugly heavy brown material grilles - but with a manual! No fuses in these, but booklet recommends installing your own in-line fuse holders (!?). Specifies a BUSS AGC-3 fuse for amps under 50wpc; or a MDL-2 fuse for amps over 50 wpc. Can be placed is series with either or the two signal wires. Very strange.... Robin

Blown subwoofer fuse..

Well, it should state in the manual what the replacement fuse is.

There might be a fuse holder near the pwr. plug. , Or near the controls for it. If not....

You might have to open up the sub unit ....and find the blown fuse, and remove it to see what you have. Be sure to unplug the unit before opening it up.

Take the fuse to Radio Shack, or your local electronics supplies stores. Replace with the same, or the correct fuse.

TR-7010 sub woofer not responding

I had the same problem, so I took the back casing off. What I discovered was that a chip that connects to the board had snapped or something. This is a black chip located on the opposite side of the heat sink. I'm certain this is causing the problem. I'm being told this subwoofer has a 20 year warranty, but I'm having trouble finding contact information for the manufacturer.

The fuse is internal. You'd need to take off the cover and look inside it. If you did that and took it to an electronics repair shop, they should be able to tell you where the fuse is by looking and help you find a replacement.

Repeated fuse blowing generally indicates a blown power supply, or blown output stages or both. One thing to do is be sure that you have replaced the fuse with the correct type. A T stamped into the metal of the fuse near the rating, indicates sloblo or Time Lag fuse. A fast blo fuse, may work once, or more times, but will never replace a sloblo fuse in this type if unit. Good Luck, hope this info helps, don't hesitate to hit me back here for more help :)
