You'll have to read through the thread.

What's the number on the face of the IC that's clamped to the heatsink?

Unzip this file and play it through the ipod into the blown amp.
http://www.bcae1.com/temp/100hz300seconds.zip

Set the volume to 1/2 on the ipod. What is the AC voltage on the two metal tabs on the back of the RCA jack when playing the test tone?

Place the black probe on the RCA shield when measuring the voltage.

There's really nothing more I that I can do without having the voltage on those points (and a few others, which would be needed later).

The '6v' was the DC bias voltage on the speaker terminals. That tells me nothing about the voltage on other points.

Find a meter and post the make/model (or provide a link to information about it).

Building a new circuit would take a bit of effort. Hopefully, the op-amp in the amplifier will be sufficient. One more may have to be added but since the power supply and input circuit already exist, it will be much easier to modify this.
