audio amp

Hi, I am planning to make a DIY Audio Amplifier project following this tutorial: Guide To DIY Audio Amplifier with 2N5875 but I can't find the corresponding circuit diagram. I can't find it on Google. Where can I find this circuit diagram?

I have the Home Patrol 2 scanner. I use it in my truck and the audio just wasn't loud enough. So I purchased a Pyle 15 W audio amplifier on eBay. It's so much louder now, but at the start of each conversation, there is an objectionable pop through the speaker. It does this as soon as the squelch...
