Sam  you  are  actually  looking  for  the
310A3...  It  was  the  model  that  you  are  describing  .
The  310A2  had  no  power  supply  and  took  voltage  from  the  30K  but
  the  310a3  did  also  take  power  from  the  30K  but  was  the  only
one  with  side tone,  taken  from  the  Pocket Guide   page  10 and 11...
