Could just look the chip and to be sure on the voltage required.

I looked at the amplifier chip and it doesn't say anywhere on it what voltage it is. I am pretty sure that is must be 12v because that is what it was connected to on the old psu. It was connected to the orange and black wires on the old psu and the orange wire goes to the right side of the CDROM drive.

Below is a picture of the wires that go to the CDROM drive. You cannot see it very well but it says DC INPUT +5 GND +12 on the CDROM where the power connector goes to it. I used paint to edit the picture so I could put the writing to the left of where it is supposed to be.

Sorry I just had another look and I found a part number on one of the parts on the amplifier (the large black part) and it is a- NEC upc1185h2. I have been searching google for awhile now and the best information I have been able to find about it is- http://www.datasheetarchive.com/specsheet/UPC1185H2.html and http://www.icgo.com.cn/datasheet/html/UPC1185H2.aspx

Does that help anyone in finding out the correct voltage? Thanks

Yeah.... use the +12V source.

it should be a 12V.

you could also go to radio shack and get a mini jack to RCA adapter and hook up a surround sound reciever.

plug the mni jack into the pc's sound jack plug the rca's into the adapter and the surrond sound and connect the speakers to the surround sound and it is ready to go with surround sound.

Bad news I'm afraid. I wired it up today and turned on the power and blew up the amplifier  :timebomb:  Once I turned the PC on I heard 2 loud bangs and then quickly turned the power off. The result-


Very bad smell after it happened and one of the capacitors ended up a few feet from the amp.

Thankfully it seems that nothing else was damaged- the pc, arcade monitor and j-pac etc still work. Not sure about the speakers since I can't test them at the moment.

Guess this will teach an amature like me not to mess with things I don't understand  :applaud:

I think I will just use a set of PC speakers for awhile and not use the cabinet speakers, should be safer that way :)
