I only work with through hole components and yes the DIP8 are correct. I use perforated boards with copper dots on one side like the one depicted below
That is a circuit developed with the help of you guys here
Psst! Put bypass caps on your OP-Amps. 2 components per OP amp in your case with the +-supply. Usually 0.1 uF ceramic capacitors close to the power leads to the OP amps. Take a look here: https://www.itead.cc/open-pcb/pcb-prototyping.html for a suggested vendor for making your PCBs.
