This item is more of a reminder for me, but other folks might find this useful as well. James, AD1L, recently posted links to the service manual and schematics on the icom746pro mailing list:
The schematics are in a zip file, but the manual is a djvu file. I’d never heard of this file format before, but apparently, it’s something similar to a PDF file. To get a viewer, go to the WinDjView & MacDjView home page.

Hi Dan,
I have a copy of the ic-718 service manual in pdf format.
I would glady attach it to an email to send it to any one who would like a copy This file is appoximately10 mb. So be sure you can receive a file of this size.
Send an email to me at [email protected] or [email protected]
