  • Notes

  • The model Grundig Sonoclock 185 is for stable 50 cycle power which holds the clock to be in the exact time. For not reliable power lines (countries), Grundig installed a quarz clock and called the model 185Q. This was introduced about 1998. According to our member Hans M. Knoll, a former Grundig designing engineer, the same happened with the models Sonoclock 21 (late), Sonoclock 22 and Sonoclock 185. We miss a schematic for the quartz clock. The 9 V battery is for the clock for cases when there is a power cut or the set is unplugged. All three models mentioned were available in "Anthrazit" (black) or White.
    The newer model Conoclock 21 should not be mixed up with the model Sonoclock 21 of about 20 years earlier or the 21a. All these models were sold in several different courntries.
