schematic help

I honestly don't know how to read a schematic. I am trying to figure out how to wire this by comparing my parts with these schematics.

Here is what I have so far.

Any place where there isn't a component means I don't know what to put there. Any help would be greatly appreciated.

I went to the link on the schematic. It has a parts list here http://tangentsoft.net/audio/cmoy-tutorial/parts.html

RLED = 10 KΩ 1/4W metal film resistor
D1 = Power indicator LED, red diffused, 3mm (or green, or yellow)
IC 1 (OPA in parts list) = Dual op-amp OPA2132PA

The "1/2" bit on the IC (OPA) indicates that you have to do the amplifier sections twice, once for each channel. Since it's a dual op-amp, you use half of it for each channel.

Thanks for the info but Triton helped me figure this out. This thread can be closed.

Thanks APHawkes.
