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."
