Can I use gas discharge tubes & MOV(varistor) directly to load? Should I use both/any for voltage surge, lightning strike protection?

    Use MOV is good enough to protect power surge spike .Must choose its  surge voltage rate a bit higher than the power line voltage.

    Discharge tube has a voltage rate, it is an old device parts before the inventing of MOV or transorb diode. Choose the tube surge voltage higher than power line voltage.

    Parallel both together will be fine !!
