Smile Help wanted checking vero layout for active 4 channel mixer

I am in the process of building a 4 channel active mixer, working from the schematics trying to make my first vero strip board layouts.

I would like someone who has more experience with converting schematics to actual layouts to double check my work before I start assembling them, and suggest any improvements.

I have the schematics for the mixer and the virtual ground power splitter, my vero layouts, and the pin outs for the IC's I'm using. (all attached)


Thanks in advance

Grant

Hi, i can't see any errors in the layout I don't see track breaks under a 10k resistor under FG & 100R under GH, but i'm presuming they are there ?

I'm also presuming that ALL the inputs are being fed from line level outputs, with low resistances ?

The inputs have been done as per the schematic, and work fine, all merged down to single input, with no cross talk that I can tell (I no longer get the sound of my acoustic guitar getting altered by my bass tone knob, volumes).

Thanks for checking the layout, i'd forgotten to put in the breaks under the resistors and capacitor, they're there now in my layout.
