If you REALLY think you need to amplify it... Yes you will need caps. to isolate the DC voltages of the PC from the amp. The speaker circuits I have seen in PC's have one side of the speaker tied to +5V and the other to and emiter follower PNP transistor. Neither speaker termainal is at ground. Use two caps: |\ | \ | | | |----------------||------------> to amp | | | | |---+------------||------------> | | | | | / | | |/ | | spkr feed isolation to caps spkr -- Ken Thompson N0ITL NCR Corp. 3718 N.
