• Notes

• The popular set from the TV series "The Waltons".
  
  The cabinet is similar for the following "Walton" models:
  12-S-232
    9-S-232
    9-S-232AT
    8-A-232
    7-S-232
    7-S-232T
    7-J-232
    7-J-232T
  They are looking all the same. That's why all of them are called "Waltons" although only one thereof was in the play.
   

   The schematic diagram got corrections (red). These lines are already missing in the Zenith drawing as well as in Riders and in Beitman.
