Hi!

I soldered my first AMP3 today.. All messurements seems fine, but there is absolutly no sound at all.

0.5mA in mute
31mA in unmute
62mA if source is connected
R7 messures 1.15V
C2 = 5.12V

What can the problem be? What more to check for?

Solved the problem.. I resoldered the chip and everything seems to be working..

Must have been a dodgy soldering on one of the pins :)

ps. How do I messure the DC offset everybody is talking about?
