Whats wrong with large filter caps for Gainclone?

Joe R.

probably should be done under random noises with some concentration on the lower frequencies (a pink noise for example?).

I think it will be hard to argue, given the magnitude of the noise and its frequency distribution, that a reasonably decent amp with 50db psrr will suffer from an average PS whose fft looks like the one you presented.

What happens if you use lots of uF's in a gainclone

yup , that was the original question

well Mesh,
did u ever think why a simple op amp circuit doesnt need a 10000uf filter caps ?
thats because the size of the filter caps is depended on power output .Most chip ams are rated at < 50W so less capacitance needed , plus chip amps got good psrr and low "on" current .
One more reason : those chip amps are intended for applications that require small space ,thats why in the application notes u see small filter caps , this is the minimum size required .
there is nothing wrong with using large filter caps for any amp but too much wount do any good eather .
