Many thanks. That helped a lot. i'm still confused as to why no P-channel FETs are needed, but that is not important since I now know that they are both N channel MOSFETs.
I will most likely try the stack with the S0-8 FETs (Mini-Z) again, but will use only the N channels this time. (hope the FETs are not damaged)
I will go through the circuit that u posted again to quench my curiosity. I understand the words except for "kalo bener". Is that a name? or does it mean "if true" ?
Terima Kasih.
