Top quality...use national semi's LM4702 with MOSFET or darlington.. mosfet.. www.national.com/an/AN/AN-1645.pdf darlington... www.national.com/pf/LM/LM4702.html or browse all the amps (some discrete ones are super simple ,too) http://71.203.210.93/pdf1/Electronic...cts/Audio_amp/ Or along the lines of a 741 based one (like yours) (see attached) OS |
