Too bad about the caps. Did one or both blow - pop up the vent or swell up? Would be best to replace both in either case. Your findings about sitting cap lifetimes peaked my interest because my use and understanding is that they will typically have a lifetime service of ~150khrs (7+yrs) at max spec but should be changed at about 50-60khrs due to leakage and electrolyte & film degradation. Hi heat (above spec) will kill them faster, but never heard of sitting on a shelf too long, so I looked it up. Wiki has a bit on it but the white paper I read really talk about it. Thanks for peaking my interests and learning a bit.

I looked back at the pictures of the PS...is that homegrown? The transformer seems an odd shape- toroidal? Surprised it would take so long to get the Caps. I've used Digi-Key and Mouser for years and typically only a few days and prices are good, generally.

Overall-great progress!! Thanks for the update, look forward to seeing your machine run!! ~PJ
