It blows the fuse because a semiconductor device has developed a short (in otherwords acting like it was just a piece of wire). Because of the noise I would suspect the main amp device is the cause. It will be most likely on a heatsink.

Hi, if your PB10 doesn't have a screw near the on/off switch and its blowing fuses - then sadly the amp is junk. The amps without a screw near on/off switch use a ami module - this goes bad and there is no replacement available - thus this blows the fuse - ... Now if you have a PB10 - PB12 and its not blowing the fuse - powers up but no sound or sounds bad - then send it to Edwards Electronics - look on ebay for the info. Thanks.

Jbl eon 518s power trip on stabilizer/transformer


hell no thats a fire hazard.. I am thinking that the surge is more that that unit can handle..surge is the extra power needed to start up an electrical piece of equipment..surge can easily double the amount of power required for startup..may need a new powerstrip with a much heavier rating..

Hi, I bought a new JBL SCS 140 system with amp HK


Fuses blow when something is shorted. In this case it will be a semi-conductor of some kind. If the device uses IC for the main amplification then you are right to be worried!

The 158 amp is totally unsuitable for the JBL.
This is the specification of the JBL:
  • Recommended Amplifier Power 10 Watt
  • they are also 4 Ohm speakers.
  • 158 is: Output Impedance / Channel
    8 Ohm.

The fuse keeps blowing as soon as i power up jbl pb 12


You have an overload in the power supply or main amp of the subwoofer, often caused by short circuited transistor. Check this out by putting an ohm meter probe to each of it's legs. If it acts like you were touching the probes together you have found a guilty part.

Jbl PB12 powered sub woofer problem


These subs have had many problems, all associated with the amplifier section. PB 12's with an "M" as part of the ser. no. were assembled in Mexico and these are the ones with the amp problems. JBL fixed mine and sent it back no charge, BUT it cost me nearly $100 to send it to them in the first place. I have another one that has had no problems at all. Try sending it back for repair. At best you'll get a rebuilt unit back, at worst a substantial discount from the company for a new sub.
