[QUOTE="Ampdog, post: 34896, member: 144"] Gentlemen, Peace be unto you; no worry about starting current. Those transformers are likely to be 30W each? The primaries are then likely to have >70 ohm of resistance per primary. That gives about 1,5A maximum current that will flow for the first few cycles, quickly dimishing as the capacitor(s) charge. 1N4007 is not going to feel that. Also not to worry too much about the capacitor values. I take it that 2 caps in series are required because their voltage rating is < 350V? (can't see it mentioned). [/QUOTE]
