Blown Compression Drivers

Hi. I have a Yamaha PAS500 rig with two blown HF compression drivers. I'd like to know the tech specifications of these drivers to source replacements but can't find anything on the Yamaha site. Any ideas?

This unit features 2 -10" passive speakers and HF horn/driver. If you are blowing the HF driver, the problem is with overdriving the high range of EQ. At sustained high volumes, the voice coil of HF driver will overheat and open. If you still have effective warranty, ask Yamaha to replace drivers. Fixed,-- back off higher frequencies of EQ, turn down volume.

I get a fuzzy sound out of the right speaker. New speakers and wires so that is not the problem


it sounds like a blown channel in the amp.open the amp and see if there are any fuses that might be blown.it might be a blown capacitor which a tech should be able to easily fix

Blown fuses


Hi Anonymous. You have a few choices. You can download a PDF of the service manual ,or you can take the cover off and locate the fuse yourself. Chances are it may be more than one fuse blown. Some fuses are located under circuit boards..hard to get to. The service manual should tell you what kind of fuse you need. If you can`t replace the fuse yourself,you can always take it to an authorized service tech.

Yamaha no power


you need to check the power supply input of your amplifier using a multimeter set your tester into a dc voltage reading.then measure the power input you must have a DC voltage supply reading..open the cover check the fuse an open fuse will turn the unit to no power.there are causes of blown fuse a shorted power transistor at the circuit will blown the fuse you need to replace faulty transistors before putting up a new fuse...check also the diode at the power supply section ,faulty diode could lead to the same problem..

Amplifier do not have sound. E-mail: rigo11us@yahoo.com


You may have blown the inline fuses for output sound. Amps have alot of fuses under the hood. take the amp cover off and check all fuses are not blown / wire broke inside fuse. Some fuses are hidden under circuit boards on some amps, check everywhere possible to check all fuses. If all fuses are fine and no broken wires inside them, you may have loose connection where your speaker wire ports are inside the amp. Check they arent black or loose. if they black they are blown as there usually soldered (a silver colour)

NAD T973 amp had noise, overheated, and then blew fuse


Hi, Very unlikely your repair of the RCA caused any damaged as preamp shouldn't cause big issues in the amp and would say you right that the problem existed already. The resistor is 100 ohm 5% but there is almost definitely blown outputs to have caused it. Most electronic places should be fine to test advise and repair. Would suggest outputs and drivers, but unfortunately not always that simple. Best of luck

Blown output drivers


The transistors are 2SK405 and 2SJ115.

I fix Luxman if you dont mind sending to Vermont.

Cheers ( I hope that helps)

PEAVEY djs4 speaker QUESTION


If a speaker is "blown", there is normally an open-circuit in the voice coil, therefore it emits no sound at all. Can't discount a loose wire, but blown HF drivers are very common.

Loss of Bass


Hi there, I would think that you have blown your bass drivers in the speakers. Sometime you may have a fuse which is blown in the speaker but this is not usual. Try on another speaker if you can.
