Henry is correct.  You can order a service manual for any Sony product from:

        Sony Service Company
        Part Division
        8281 N. W. 107th Terrace
        P. O. Box 20407
        Kansas City, Missouri  64195-0407
        
        Phone information for the phone number (sorry)

The Sony manuals are absolutely beautiful.  They show an electrical schematic
diagram, P. C. etch layout, parts list, graphic signal representations, 
calibration information, operating information, specifications, dis/assembly
instructions, voltages at all nodes, ... 

I recently ordered a manual for the ICF-2010 radio receiver in conjunction
with designing a circuit to control the keyboard from a computer.  The 
information contained in the manual was so complete, that the entire design
could be engineered without physically measuring voltages on the circuit
boards.  The cost was only about $5.  

I fabricated the interface circuitry using surface mount components and tucked
it into the radio cabinet.  Now I can completely control the radio from a data
base running under UNIX.  The data base is programmed to display a list of
international shortwave broadcast stations actively broadcasting in English at
the current time. One simply chooses a country and it is instantly tuned-in.
