  • Notes

  • The origin of this model is Step by Step kit no. 4. The Vice Versa part is the extension to an intercom with 1 up to 11 extra loudspeakers. Also an extra bell can be mounted for calling up. The last schematic describes in detail how to connect the speakers. In other words: the SBS 4 is an intercom - radio combination.

    The GFT-type Amroh transistors can be replaced by respectively OC3, OC4 and 2N408.
