Most service manuals and schematics are PDF files, so You will need Adobre Acrobat Reader to view : Acrobat Download Some of the files are DjVu format. Readers and resources available here : DjVu Resources
For the compressed files, most common are zip and rar. Please, extract files with Your favorite compression software ( WinZip, WinRAR ... ) before viewing. If a document has multiple parts, You should download all, before extracting.
Good luck. Repair on Your own risk. Make sure You know what You are doing.

General purpose transistors (dual transistors)


    Two DTA143T chips in a package
    Mounting possible with SOT-363 automatic mounting machines.
    Transistor elements are independent, eliminating interference.
    Mounting cost and area be cut in half.
