[QUOTE="tangmonster, post: 179680, member: 1581"] the other option is to buy a bunch of resistors extra en get a decent multimeter and measure and get 3 resistors that measure VERY close. This is cheaper than buying 0.1% resistors. ONce you get the board post the schematic here ,and i will tell you which resistors is important. The ebay circuit uses this circuit diagram: [IMG]http://www.shine7.com/audio/pa150_schematic.gif[/IMG] R3 ,and R2 is the important resistors (same for the other two lm3886's onm the pcb) the 3 pots on the pcb is to set the DC output voltage of all three chips to the same. You will need a good millivolt mutimeter for this. [/QUOTE]
