  • Notes

  • Beitman R-16 shows the following models for this schematic: chassis HS-431 for the four models: 56H1 Mahogany, 56H2 White, 56H3 Green and 56H4 Turquoise. They are otherwise exactly the same, having a big center knob and two small knobs far on the edges on the same hight.

    But this chassis HS-487 with the same schematic was used for quite a different cabinet with two knobs besides each other just above the feet. See the pictures. The HS-487 chassis was used for the models 56R1 Ebony, 56R2 White, 56R3 Red and 56R4 in Green.
    This model is in color White.

    AC-DC Operated AM Superheterodyne Receiver.
