hey guys,
i just got a really good circuit simulator at
http://www.falstad.com/circuit/ and i simulated this amp but the gain was really below 1 so a few questions
1. What is the RMS value of an audio signal output of an IPOD or computer output.
2. At 2.26 V (2.0AC + 0.26DC offset simulation) output the RMS of the amp is about 700mV with a 32Ohm load. Can this be loud enough to drive headphones ??
3.What does the capacitor (0.1u) with the power do?
goto to this site and when the applet opens click on file then import >> select this text and paste it and click import

ps wait for the circuit to stabilize and then check the output
Thanks
