  • Notes

  • 136S adapted for mains supply. Knobs are spring fitted.
    Same case for 106(1946), 126(1947), 136L(1948), 136S(1948), 236L(1949) and 236S(1949), except the 106 has a different grill. The case has a hole for the wavechange on the 136 and 236 models. The S versions (LW instead of SW) have the turns of the loop aerial in parallel and usually have an aerial and earth socket under the grill.

    Uses a docking Mains PSU 306, so this model can be distinguished from the others by the four power sockets in the base and a release tab on the bottom front. See also the original Personal 106 for more information.
