usually the main filter cap is always good, just replace the brown leaky ELNA ones.

the only problem you may find during the process is a corroded circuit board, just spend more time cleaning it and sealing it, if necessary.

As for current limiting, there should be a trimmer on top of the controller board, see my videos, just turn it down, you should make a cable adapter that enables you to measure the current while plugged to a load. let me know if you need more informations!

make sure you don't short the power supply with the multimeter while checking current

on all the brick I repaired, none of them needed adjusting, since the powerbooks will accept a wide range of voltages and the fact that the voltage dips down while under load

uniserver, if you need Mac Portable bricks, just open one of the PowerBook ones and tweak the trimmer inside to adjust the current limit.

Should i do a video about that too? but I don't have a Mac Portable (Yet... still looking for one...)
