I found this mixer at http://www.circuit-finder.com/categ.../mini-stereo-mixer-mic-line-for-pc-audio-card which had several features/considerations that suited my needs. I only missed on the op-amp because I don't have any. I have some 4558, 358 and TL072 and some more of the common type (99% of my parts come from dumpster dives). If I just ignore the chip specified by the schematic, and use some 358 chips instead, how would this affect the operation of this mixer? Is it possible to adjust any component values or make very minor changes that would allow using the above chips?
I am not going to be using the section for mic input (upper left), and instead wish to make 2 of the line inputs (instead of just one as shown in the schematic).
Thanks for reading this post.
