  • Notes

  • The components of this intercom system are mounted on a pertinax strip. Two identical units are necessary to build a complete intercom system.

    Each unit is built into a metal cigar box.

    The original article in Radio Blan lists two transistors GFT25/15 (the last two digits relate to Umax).
