Amplifier Capacitor voltage recommendation (Mundorf/Nichicon)

Since it is a dual rail design, it uses two sets of capacitors. The low voltage rail (+/-36V) uses 6 caps for positive rail and another 6 caps for negative rail. When we look at the high voltage rails (+/-72V), it uses another 6+6 caps. The caps are wired between the 36V rail and the 72V rail, so the caps themselves only see 36V even though they are filtering for the 72V

What does the Voltage Rating on a Capacitor Mean?

The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc.) at a certain voltage (10V, 25V, 50V, etc.). So
