I'm going to build a new preamp which will contain 7 dual opamps (TL072 and NJM2068 .... yes, it is a low cost project).
The opamp stages will work as
- mono summer
- 3 way 24db x-over
- output buffers.
That thing will be powered by two 9V batteries with a center tap.
Should i add capacitors to the +- power rails to gnd at each opamp?
Or is it not neccesary with the batteries?
Which capacitor type and which value would be best?
