To Mitchell,

Power supply capacitor mods can often improve things, but you should
read about power supply design before jumping into things. Yes,
increasing the size of the power supply filter capacitors might improve
things, but making them too large may introduce a rectifier failure
problem that will catch you by surprise.

Very true. Increasing the size isn't always a benefit. In some cases,
increasing the size will also increase the ESL, which could actually
introduce more ripple into the system.
