My Sony Vaio laptop /standard charger set up has always worked beautifully in all classics.
The socket, by the FE's right leg (when he's flying sideways) is standard American domestic female... no rude comments about our oversize cousins please.
Anyway, no need to know where it is, just dangle the plug over your right shoulder and say "Plug me in and I'll show you something that'll make your eyes light up"
You might be pleasantly surprised at the astonishing alacrity from what you thought was just an ancient form of crustacean lurking behind you :-)
