Message Date From Subject 12156 2016-01-03 17:50:31 Bill Meara Building R2 -- Replacement for LM387? I am resisting the temptation to jus throw any old AF amp in there. I know Rick worked hard to come up with a quality AF amplifier circuit. But the LM387 isn't around anymore. Any suggestions for a replacement or equivalent IC? Thanks, Bill N2CQR 12157 2016-01-03 18:28:17 K5ESS Re: Building R2 -- Replacement for LM387?
Well the NE5532 is a low noise amp (a little better than the LM387 I think) and it’s used in many of the audio circuits in the EMRFD book. It’s not pin compatible with the ‘387 though.
