huangyong 0 Report post Posted November 20, 2003 transistor??!!?? do you mean the 3 pin thing?? i think it's a voltage regulator. and the 78xx, xx is stand for the output voltage i suppose. and this is a single power supply , rite?? tropicalrips, you can change the brand & value of c1, c2 to make it more audiophile.... hehe... transformer as well... i've built one also, just bought the board and got other components myself.

tropicalrips 0 Report post Posted November 20, 2003 (edited) me not electronics, me electrical so is it a transistor or voltage regulator? also what is the round thing with 4 pins? the parts list i saw "bridge" is that it? i'm not sure what is single power supply, but the lady did ask me if i want + or - so she can chose the "3 pin thing" for me do u mean c2,c3 huangyong? so it can drive headphones?
