[AMRadio] Variac hook up

[russ dworakowski]

Steve,  using a ohmmeter,  Find out  which  terminal is  the  wiper arm-
this  is the  hot side of  the output.  The cold  side of  the  output
is  also  the neutral  terminal.  The other side  of  the  winding  is  the  
hot  side of  the line.    Again  hook up  the  line  side  to
each  end of  the  windings,  the  neutral  side  is  common  to input  and  
output.  The  output terminals  are  the   wiper  and  neutral.
Russ.
