Vietnam also uses 2 round pin 220VAC sockets in most places.

Subject: [Amps] More on two pin 220vac
Sorry to belabor this some, but if we read Mr. Parascondola's first message
about the presence of voltage inside some Ameritron amplifiers, he seemed to
say that it did matter which side of the hot and neutral of the two-wire
supply 220ACV was connected to the amplifier AC input. Does it matter?
Please comment if this above statement is true or false. Thanks.
Note that some Ameritron amplifiers fuse only one side of the incoming
220VAC.
Clearly u guys have never been to many places in the world. YES YES YES
about 80% of Thailand buildings have TWO holes in the 220VAC wall sockets
and ONLY TWO HOLES. One side is definitely hot and the other side is
definitely neutral. The pin sockets, the holes, are not marked and not
keyed in any way. There is NO GROUND present by any means...no wire ground,
no BX cable nor conduit. You can NOT obtain 110VAC by splitting the 220VAC
with one side to the hot and one side to ground because the voltage between
the pins is 220VAC and the voltage between the hot pin and earth ground is
220VAC. Neutral pin to earth ground is about 8VAC but that varies from
location to location.
Please read my exacting language carefully. Thank you very much.

P.S. An extra fun note is that the "outlet strips" sold in Thailand have
holes in the sockets for a ground pin, but the strip has only two wires from
the strip to the plug for the wall. Further, the type of strips sold here
for spike protection and other ground related functions (RFI killing, etc.)
do have a three wire plug, but they plug into a two wire socket with no
ground. Makes me wonder is there is any protection function of these three
wire "outlet strips."
