• Notes

• "See thru" transistorized blocks that connect magnetically to form working experiments that you can see and hear - developed by Egger (-Lectron), Germany.
  Macalaster Scientific Co., a division of Raytheon Education Co., imported this system and developed the special instruction manual and the Supplementary Instruction Manual 1.
  This Add-On #7 Box - combined with Series 3 - allowed additional experiments.
  A Series 3 Set may be upgraded with Add-On #6 and Add-On #7 to a Series 3A set with 64 projects / experiments. Then there are two tuning blocks and two HF transistors for experiment #33: "narrow band radio receiver".
