Disconnecting or reconnecting any receiver electrical plug or other electricalconnection.c. Connecting a test substitute in parallel with an electrolytic capacitor in the receiver.CAUTION: A wrong part substitution or incorrect polarity installation of electrolyticcapacitors may result in an explosion hazard.2. Test high voltage only by measuring it with an appropriate high voltage meter or othervoltage measuring device (DVM, FETVOM, etc) equipped with a suitable high voltageprobe.Do not test high voltage by "drawing an arc".5. Do not defeat any plug/socket B+ voltage interlocks with which receivers covered by thisservice manual might be equipped.8VHZLWKWKLVUHFHLYHURQO\WKHWHVW¿[WXUHVVSHFL¿HGLQWKLVVHUYLFHPDQXDOCAUTION: 'RQRWFRQQHFWWKHWHVW¿[WXUHJURXQGVWUDSWRDQ\KHDWVLQNLQWKLVUHFeiver.3.
