A few manuals I have available:

• FT-757GX Transceiver Service Manual & Schematics (9.6 MB PDF)
• FC-757AT Automatic Antenna Tuner User Manual & Schematics (4.4MB PDF)
• FC-747 Transceiver Schematics (2.3 MB PDF)

These are PDF and can be opened with Adobe Acrobat Reader. I highly recommend to RIGHT click it and "Save as" instead of opening them directly from the browser.

PLEASE if you intend to put the manuals in your site, do NOT link directly from your website to the archive. Instead save it to your hosting to avoid killing my bandwidth.

I hope you may find them usefull. 73!
