As part of the maintenance of cassette drives, the complete drive mechanism is serviced. This includes thorough cleaning, the exchange of susceptible plastic parts and the treatment of certain components with application -specific fat or Oil. To ensure a reliable function, the straps are renewed. The pressure roles are inspected and even renewed if necessary. After maintenance, each drive is measured with high -quality test cassettes (level, tape speed and azimuth (optimal reproduction of the high frequencies))) and operated in a longer test run. We can sometimes determine the quality of the clay head about the recording quality of a high -frequency sinus. Based on this data, we decide, among other things, whether the device is still suitable for a sale. The devices are presentable .
