Capacitors...

The amps I am building call for a 390uf 450v cap(seven per amp) and I am wondering which brand is best, and if I can get better performance from say a 450v 500uf or even a 450v 1k uf cap...

Re: Capacitors...

THIS CAP has the highest ripple current in the class you were looking at. Couldn't find its ESR listed (probably not the lowest). Is this a power supply cap? How much current does it need to draw?
It should sound like it isn't there!
