Take a look in your scrap electronics. When my friends "professional" subwoofer went out, I took a 4558 out of a galaxy to fix it (his DJ partner was an idiot pushing too much power into it). Later, I found about 6 more 4558's in a home theater system that had failed (the 4558's were good still). If it handles audio, chances are there is a 4558 inside. They were very common and found in just about everything audio related that's about 8-15 years old.
