Schemo for M-Audio speakers?

[BradAvenson]

Anybody have a schematic for those little M-Audio speakers. One of mine I think has gone to DC on the woofer.

Thanks,

OK, well it looks like the flimsy PCB has something to do with it. The thing works when you take the pcb off of the back plate. I'll see if there is any cracked traces or such.

Any other suggestions?

All fixed. So just FYI.

Its based around the LM3886 power amp chips. I reenforced the traces from the +in,-in and output pins and the problem dissapeared. So I guess a cracked trace because of they way they mounted the PCB.
