This is one of those "it's cheaper to replace the speakers" scenarios as these units can be had for $25 new, and for even less on E-Bay.

Power trafo altec lansing atp3


Is the label missing? All the information is printed on a label or stamped into the plastic housing. Have you opened it? Many have an internal fuse you can replace.

How can my laptop charger fit to computer speaker?


Please do not modify your laptop charger to power your speakers. The laptop charger probably has too high a voltage and amperage output. (USB chargers don't provide a large enough output.) The Altec Lansing ACS40 speakers need a 15V 900 mA power transformer; the coaxial power connector has the positive voltage on the center pin. The model number on the transformer is 4815090R3CT . This is available through Amazon.com and other vendors. One vendor is http://www.emtcompany.com/altec-lansing-4815090r3cac-power-supply-charger-adapter/1010666.html .

I hope this helps.

The transformer of my sub-woofer is burnt. When i take it to the repair shop, they say that the transformer is not available. I badly need to fix the speaker as i love them very much and the new ones are...


Sub woofers have small amplifiers , not transformers. The amplifier is removable and replaceable. The The overall size and the output wattage are the spec's you need . The output wattage is on the label which is attached somewhere on the speaker. You do NOT need to replace the amp with the Altec Lansing brand. Have you contacted Altec Lansing to purchase a replacement Amp? That's where I would start. If they cannot help you I would Google replacement amp sub-woofer, Altec Lansing model MX5021.
good luck

Altec Lansing computer speakers , power requirements


You have to find out what the speakers are rated at then go form there. There is usually a placard or sticker on the back that says what watts and voltage they are rated at. Then you have to find out what plug goes in. Or you just buy an OEM plug
