[QUOTE="thylantyr, post: 2272495, member: 560358"] I know this is hard, but check out this schematic, a common SS amp. [URL="http://www.leonaudio.gr/images/4x50sch1.JPG"]http://www.leonaudio.gr/images/4x50sch1.JPG[/URL] Text book design, 3 stage. R6 and R8 ratio determine gain. If you look closely, R8 connects to the output which makes it the feedback resistor for the input stage. You can raise R6 in resistance to lower gain or reduce R8 or any combination of the two. Common sense rule says that increase R6 is ideal because decreasing R8 can drive transistor Q2 with more current. In other words, changing one resistor in a preamp or power amp can allow you to opimize your noise and get better results.
