In most switching supplies, the 120-Vac or 240-Vac input first passes through a fuse and a line filter. The ac input is then rectified by a full-wave bridge rectifier and filtered by a pair of high-voltage capacitors. This creates two high-voltage sources from either side of the full-wave bridge, one positive and the other negative.

• Capacitor fuses see almost continuous full load (when the capacitor is switched in). • Capacitor fuses tend to be bigger. The most common transformer sizes are 25 and 50 kVA, usually with less than a 15 A fuse. Typical capacitor sizes are 300 to 1200 kvar with 15 to 65 A fuses. • Both have inrush; a capacitor''s is quicker.

Safety capacitors for EMI filtering and voltage isolation
They are classified according to their use in the circuit. Capacitors connected line-to-line are called "X capacitors," also called "line to neutral" capacitors. Those connected from line-to-ground are called "Y capacitors," also called "line bypass capacitors." X capacitors are used for differential-mode EMI filtering.

A capacitor is not a fuse. Unlike a fuse it is undocumented how a capacitor fails. What I mean to say is: - when a fuse fails, it breaks the circuit and the circuit it safe. - when a capacitor fails, it may either break the circuit or short it.

Tube Amplifier Safety
Drain the Filter Capacitors. The filter capacitors in an amp store enough high voltage DC to kill you, even when the amplifier is unplugged so you must check them for residual DC voltage and drain them if voltage above 30 volts DC is detected. Capacitors can hold their charge for days. Filter Capacitors in the Fender 5E3 Deluxe
