ok, so its possible with a large amount of small paralleled electrolytics you could achieve something similar, thats something to explore.

I cant take a pic right now but will soon, its a bit of a mess with everything wired point to point.

The chips are on DIP8 adapters, and oscon soldered directly to pins/pad, its satisfying that this kind of rough circuit building can allow even closer decoupling with the oscon than what possible on a PCB.

From the LT3045 board output there is a twisted pair to the huge film caps, the chips have individual wires also directly to the LT3045 output, instead of the legs of the film caps as the chip power wires are shorter this way with the big film caps out of the way, if that makes sense.
