wwenze 0 Report post Posted November 9, 2008 In the cheaper non-portable amps and in the rubbish bins of those who upgraded their devices. You can get it at farnell and probably SLT also, high chance koba will also have it, because it's widely used and cheap. But why would you want to get it when much better alternatives just cost a few bucks more. Share this post Link to post Share on other sites

wwenze 0 Report post Posted November 13, 2008 sg.farnell.com is a good place. My idea when buying chip op-amp, is cos they are so cheap yet so important, might as well go for the best save for a few that are really expensive. LM4562, OPA2107, OPA2132/2134, AD823, AD843, AD8610, LT1361/1364/1469 and the most expensive, OPA627 x 2 are all good chips, or go a step further and http://www.audio-gd.com/enweb/pro/diy/OPA.htm to order a cheap discreet op-amp. Please go search reviews for their sound, it's too much to type here. Share this post Link to post Share on other sites
