Two last questions on my power supply project. Is it worth putting an inrush current limiter http://www.produktinfo.conrad.com/da...B_250V_16A.pdf in with the power supply. The transformer will be 500va 2x18v 35amp 600v bridge rectifier 3 x 4700uf 100v caps. Is a heat sink needed for the rectifier or is it enough to bolt the rectifier to the metal case ?

Cheers in advance
