500V Dual-Section Cans

Has anyone here used two dual section cans tied together to replace a quad cap can. I have seen where one guy doing a custom ST70 laid out what appears to be two JJ cans under chassis. [didn't want to post his pics]
If so how are they tied and what values do we want to shoot for, exact voltage and uf or improvise above Dynaco replacement values.
Looking to do a custom layout with under chassis power supply and trying to not use a cap board.
example pricing from "a site" these are clamp mounted solder lugs
100uF+100uF 500V JJ Can Ecap $11.69
50uF+50uF 500V JJ Can Ecap $9.89

Hi:

Saw the custom layout on http://wardsweb.org/audio/ST70/ very nice looking stuff. The cans caught my eye and hence my post. I think they are JJ cans http://www.jj-electronic.com/
