Let's see.. there's a bunch of op-amps that come to mind... there's 'audiophile' amps out there, and there's just instrumentation stuff... the LM324 is pretty common, as well as the LM1458 and it's cousin the LF353 (JFET inputs). NE5532 is an audiophile part, but certainly works as well. They are really easy to use; gain is set by resistors typically. Some of them are single supply, others are dual supply. -- Kris Kirby <[EMAIL PROTECTED]>
