The caps can be several uF, but see the tweak post below:

as for their rating, IF you use the specified RS transformers, and fuse the primary of the input transformer, then use of a qualityt film cap rated at 160VAC and 250VDC should suffice. Be sure to use the damping resistor if the cap is bigger than 0.1 uF.
