Here in this photo below, the Tantalums
are only on the bridge wire...
I want to test this a little further to document the results for you guys, first results were good and the PS3 booted and worked fine, with 8 of these proto-types. I did one for every NEC replacement.
It's for those using bridge wires:- if we look at the way the NECs work, and what their role is, then adding a bridge wire can be counter-productive for our Tantalums unless done correctly. Because if we give the current the option (a route) to leap-frog (by-pass) the filtering capacitors and go straight to the RSX / CELL, then the processors won't work correctly, because the current is fluctuating all over the place and the line is too noisey.
Adding a bridge wire (incorrectly) is like having little, to no capacitors at all...
The current will always take the path of least resistance, so we need to force the current through the filtering process of the capacitors, with no other options / routes, and only then arrive at the RSX or CELL once filtered. That's how those processors want it so they can function correctly.
I tried this concept on my 1st PS3, i did all 8 x NEC replacements with this idea, Tantalums only on the bridge wire(s), like this photo is showing for 1 x NEC replacement, it was all like that (x 8) and it worked, the PS3 booted up, and worked fine! Originally for that test i had used size B Tantalums, and in this photo it's those 'Panasonic' size D ones - this photo below is just to give an idea of how the concept / idea was installed / looks)
However, the same day i had just received the "new" NECs from China in the mail, and i was too excited to wait any longer, so i took out my test bridge-wire Tantalums and soldered the "new" 8 x NECs, and that worked too, but now i can't de-solder the "new" NECs and they are stuck there, so i am working on another (2nd) PS3 to hopefully show the test results again, with photos etc, of this Tantalum only on the bridge wire idea working.
I also want to add an array of MLCCs (0.01uF to 1uF) to this proto-type, will aim to report back the results soon, all being well, but it might be some time yet because i have some other commitments (work) that i need to sort out first.

Here are all 8 of them, that i installed together for the original test, the PS3 booted and worked.

Thank-You, guys so much, truely i mean it, i would never have spotted those stupid mistakes without your help, and i would have continued testing the PS3 for days like that. Now i can go sort that out without causing any more damage. Back soon, all being well.
