what are these ic's? Answered
i have puled two components out of an old radio/amp/ cd player etc. and i want to know what they are and if i can use them to make an audio amplifier. one says BC Power Module SVI 3101 D on the front and 424 1w2 on the back and has 14 legs (it can be seen here, this is actually the exact one i have from the same appliance : http://farm2.static.flickr.com/1042/4733036801_a2d72f1df9.jpg ) . The other looks kind of like an op amp, it has 12 pins and the part no 5a3920, and below that 218 130a (as you can tell i am not a good at desoldering and not having a solder suck doesn't help).
