I had my CD player apart trying to locate the output opamps, hoping that substituting better ones would be a simple matter. All I found that might be the right things were two six pin (single row - looked like a resistor array) IC labelled "C457OHA" also there was a "88O7N" on them... might this be the op amp, and if so, is is pin compatible with the popular replacement opamps? Oh, the CD player is a Nak OMS1A. Thanks.. -- ______________________________________________________ | Travis Stansbury, Yale '94 || 2358 Yale Station | | travis@minerva.cis.yale.edu || New Haven, CT 06520 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
