They are usually across the mains and sometimes between the mains and earth for static earthing.
All you need to do is check the thyristor with a meter between the case and the other two pins and make sure there is no short circuit and then from a good quality component supplier buy some more class X2 capacitors to replace them.
Between the pins on the thyristor will give a low reading. The thyristor could optionally be checked with a battery and bulb with reference to the data sheet but it is unlikely to be faulty if it is only the mains filter capacitor that has blown up.
