rebuilding schematic/ pc board
Removing 1 op amp and moving things around and got to wondering why is R16 and C8 in circuit?
the mixer I posted has these componets but in simulating I see no difference with or without?6 Input Mixer by IC 741 , LF351 ,TL071 Circuit Project Electronic trying to cut down on number of IC's for more pc board real estate. I presently have 4 stereo inputs utilizing 2 1/2 TLo74's using the revised mixer I can eliminate at least 1 TL074. |
