you should use a volt-meter and check the caps plz, if they are still charged apple is more BS than they could ever be, first year in electronics engineering and they teach people about "bleeding" resistors, that should discharge caps within 10mins MAX when unplugged so plz check it out for me (but be extra careful).
the shielding could stop EMI from the transformer except just protect people so IF they have such a resistor they should still have it.
you should also check if this thing really Fcc and ce compatible
