g. X-radiation – TUBE: The primary source of X-
radiation in this receiver is the picture tube. The tube
utilized for the above mentioned function in this
chassis is specially constructed to limit X-radiation
emissions.
For continued X-radiation protection, the replacement
tube must be the same type as the original, Sharp
approved type.
When troubleshooting and making test measure-
ments in a receiver with a problem of excessive high
voltage, avoid being unnecessarily close to the pic-
ture tube and the high voltage component.
Do not operate the chassis longer than is necessary
to locate the cause of excessive voltage.
