My guess is you'd be looking at 0.2-1.0uF. It will increase the output voltage somewhat and also increase the output impedance of the PS by a small amount. Be sure to use a cap that is rated for high ripple current. Some of my projects that are designs of Kevin's use a Gentech 1.0uF cap that he favors and the big mono-blocks with a 600V B+ use 850V rated GE 0.68uF caps. Morgan Jones 4th ed. has a graph that illustrates the change in voltage and output impedance with different cap values.
