The chokes used are 5 Henrys or greater, so their impedance at 60 Hz is greater than 1800 ohms and the current at 120 volts is less than 64 mA (reactive).
These chokes look like power transformers but without secondary windings. Their parasitic capacitance is what makes them act as filters for high frequency electrical noise.
You may add a fuse if you like, but be aware that many fuses degrade audio performance.
