Capacitor proximity to power and ground

[leftbldg]

For my first CMOY (using tangent's guide) I've modified the 276-150 board layout to place the power supply caps further out from the center ground bus so I can shave a few rows off the board at the other end. I"m using the 220uf caps recommended in tangent's guide (35V), and after moving them out (by moving the jumpers to go to the outside pads) they are each 10-12mm further from the virtual ground and a bit further from V+ and V- inputs. The PS is working fine with a 9v (+4.77, -4.77 measure on DMM).

Is there a performance consequence to locating the caps farther from Vo/inputs? If so, what is it? TIA

If they moved closer to the op-amp, that's better.

But even if they moved the other way, it's probably irrelevant. If moving the big electrolytics farther from the op-amps caused problems, moving them back isn't the right thing: it speaks of a borderline-stable design, which should be fixed another way than moving the big electrolytics around. The right solution in that case would be to add some small, fast bypass caps right near the chip. Then the electrolytics can be many inches away and it won't matter.
