Hello guys, i'm new here. Here is my first class AB, it works pretty well, but it distort a lot when raising the volume giving me something about 4-5 watt clear on a 36v 1A PSU. The heat it's not excessive, the 20 wat power is there but sounds bad. here's the schematic: This is the first version, where the small transistor (pre) has on the base a 1 MOhm resitor (now is 100 KOhm and sounds better) and a 500 KOhm resistor that i've removed. The problem is "Where is my power??", any help would be apreciated a lot.
