Altec Lansing ACS 54 Transistor Question

Hi, I have a set of the ACS 54 speakers, and one of the small transistors has perished. I am fine with replacing it, but I don't know the number of the part. When it died, part of the surface melted so I can't read the numbers on it. If there is a common cause of this part failing can you please let me know, otherwise just the number of it will help me get going. Or, even just a schematic diagram would be fine as well. Please refer to attached picture if needed. Thanks for any help, Rick

Vista messed up speakers


hi Avsandrick
Happy Holidays!
Doing a driver search don't help much, so I recommend 2 things here, wait until MS, make a Service Pack Cd, for Vista, or go to the Altec Lansing Page and see if for your particular model, there are drivers for vista.
other than that, a generic sound driver, could fix the problem.
