    A question: since the relays seems to be the largest expense if building a few of these, would it make sense to go for a slightly larger but cheaper relay? For example: http://se.mouser.com/ProductDetail/KEMET-NEC-TOKIN/EE2-45TNU/?qs=sGAEpiMZZMs3UE%252bXNiFaVLHF5q190qntaE86wsYZ%2ffA%3d I'm not fully sure this part would work, so apologies if I don't have the spec right. If it does, it would make the board roughly 15 mm longer (bad) but save 25-30 euro on the relay cost (good)...

    And here's input from Mundorf: "Thank you for your interest in our articles. The higher VDC shows the surge voltage, the lower the rated voltage. For more details about our MLYTIC capacitors please download our newest catalogue at this link: http://www.mundorf.com/PDF/Mundorf_Fidelity_Components_Catalog.pdf " "The actual available item are shown in the catalogue, NOT on the homepage. The last price changes were at June 6th, also there were changes in the delivery program." 4-pin power caps are at page 27. Unfortunately, the 680 uF seems no longer to be in the standard list, so no clarity there... On the other hand, if Mundorf then custom makes these for batch orders, their spec would be ground truth, so no problem left to solve. Sorry for making a fuzz about this.

    Yes, I saw that data sheet, and noted that surge voltage is 550V (605 for the other sizes) even if the first column says 500V rated voltage, so technically it should be fine if maybe close. My question was more about Mundorf's latest data sheet (same as website "http://www.mundorf.com/en/?category=hifi&menu=caps_power&content=mlytic_hv_4pin, more recent version than partsconnexion sheet?), where VDC in the third column is 550V for all, but the first column order code implies that the 680uF might be rated 500V rather than 550. For any other component on that board I would not care, but these caps... Since some sellers seem to go by the order code, I though it worth checking out. Anyway, you're certainly right, it's much more likely that sellers have misread the order code than that Mundorf has screwed up their VDC rating table. I might send an e-mail to Mundorf just to make sure though.

    Somewhere there is a typo: the order code above for the 680 says +500 even though VDC says 550, and some vendors have the 680 listed as 500V, e.g. http://www.partsconnexion.com/capacitor_ele_mundorf_hv+.html MLGO+500-680 680 ±20% 550 35 * 100 1.2 * 9 51.90 @Sorenb: would you know which is right?

    Checked and updated my list entries. Definitely a YES in the yes column.

    Thanks for organizing this! I'm in for 2 amp boards and pair of fat power supply boards. Edit: V3 of the boards preferred, but V2 is great too!
