Hey guys, nice work. I hope this solves the problem for everyone and we can get back to business.
Holland is right about the cap voltage. It may be hard to fit a 50V cap into the space available, even with a smaller diode so if you can't then use 35V. As long as the voltage stays below 35V you're probably ok. Temperature has a much larger effect on the life of electrolytics than voltage. But, running a 35V cap at close 35V will shorten its life.
When wiatrob is ready to make new boards we can address this problem. Hopefully there is enough room to move things around for this cap.
