Little .Audio. Amp

Found this little "gem" on the net from a seemingly reputable website. The author boasted a 45dB gain from a low-power device to a small speaker. I dunno about that- I had this thing in a breadboard for a little while as well as modeling it here for simulation. I'll just say neither one worked out as I had hoped. However i'm still pretty new at messin' with amplifiers so, anyone wanna chime in about this here little amplificator? What's up with the square wave on the output?..

The square wave is probably just clipping. ie: the amplified signal exceeds the maximum output voltage (depends on supply and actual circuit) . Drop the input voltage to 4mV and check it again.

Hey Sine, may I recommend some really beneficial study material, I really don't mind making a few recommendations to those who need it the most?

Posting snide remarks is cowardly my friend, why don't you learn basic reasoning skills and try again...

I'll repost this again; Fools such as Sine_eyed are individuals who have disengaged their reasoning skills or simply don't have any, fortunately this problem is restricted to a minority. Snide remarks, contentious comments and demeaning statements are all symptomatic of the lack of reasoning skills. Knowledge in the absence of reasoning skills is moot, anyway, given their reluctance to reason with anyone who opposes their ideology, they have ostracised themselves from the rest of the community who posses reasoning skills. Cheerleading anyone who cannot reason with anyone who opposes their views is detestable.
