Mods.dk probably has it.
Also...
Please remember that Google is your friend:
try Google "kenwood tr-7730 service manual"
BUT BE CAREFUL. On some sites the big, obvious "DOWNLOAD" buttion is for something else. The real download is in "fine print" somewhere else:
e.g. this operator's manual: http://elektrotanya.com/kenwood_tr-7730_sm.pdf/download.html
Poor resolution Schematic:
