For fun I've constructed this simple amp: http://www.eleccircuit.com/simple-preamplifier-circuits-by-transistors/
The one with 2 bc547s. It dosn't work at all. Yes I have studdied transistors and biasing and design etc but i'm still a newb to it.
Is this circuit bs? I built it exactly as it should be. The grammar on that page is bad so maybe I shouldn't expect a good result? Btw, I used an 8 ohm .1w speaker on the output and a laptop for the input. Is it possible the laptop voltage signal is much too small? My oscope said the audio voltage from my laptop was under a volt in the millivolt range but I cannot recall the actual voltage.
