i knew about your amp project so when i saw the thread i thought i would see if i could help,,i have googled and searched for quite awhile,,it is suprisingly hard to find a pic or even a good diagram, of that part of the psp and even harder for the slim.
with all the information on this site i am realy suprised the tut section doesnt have this info as well, also i have noticed there is only a few pics of the powerboard and 5v points,could someone post some pics of mods in progress to give us modders that are new some more pics to go off of and maybe some different soldering points and wire routing techniques.
folklord sorryy for the long post that was of no real help to you
