But I guess I will hopefully find out tomorrow.... that is if I ask the lady who does rework stuff.. I'm scared of her
I now get it all - mucho gracias! So is the DPAK transistor (and whatever is used to dump its heat) the limiting factor, or are there other small parts in there that might not handle the higher requirements? What would be the theoritical limit the Aquaero w/ Powerboost and the T0-220 transistor can handle? I assume it would at least allow 2 DDC 3.25 or D5s, but I could be wrong.

Anyway, I'll let this sit for now so you can go to bed and get the courage to talk to the scary lady tomorrow
