    HELP!!! I am a complete novice with electronics. I’ve only recently started teaching myself how to solder electronics, so I don’t have a bag of troubleshooting tricks…I have now built the amplifier twice (brand new from scratch) and am having the exact same problem both times. I’ve connected the amplifier to a pair of .5W 80hm speakers (from sparkfun). Each speaker produces a thumping noise, one louder than the other. I am using two 9V batteries for power and connecting my iPod through a 3.5mm audio jack. I am absolutely sure that I soldered all parts correctly, especially the second time around. I have swapped out a different speaker, to rule out speaker issues, and have soldered two different audio jacks. I cannot figure out the problem.

    Can someone please tell me what I am doing wrong?? Thanks!
