Good news everyone ! </farnsworth>
Many years ago, as I started my journey into this FM synths deep rabbit hole, I've been welcomed by friendly people from next to my home to the other side of the ocean and I got many helpful answers to my many questions.
Time passes and now it's time for me to give back to all of you and especially to Daniel Forr
ó whom gave me precious tips and documentation to fix my TX816 back in the days.
Without further ado I have the honour of releasing a better quality (600x600dpi) scan of the TX816 service manual in full including it's oversize schematics ! I bought it on the web few months ago along some other rare Yamaha documents (that I intend to scan also) and it took me few hours of scanning and stitching (and few minutes of swearing also). I hope that it'll help anyone who have to fix or enhance this mighty Yamaha workhorse !
You'll find the link here: https://archive.org/details/tx-816-service-manual (as the schematics are 40MiB and the manual 125MiB I couldn't upload them here, feel free to copy/host them elsewhere)
This put an end to a quest I started 3 years ago to get a better quality PDF of this manual in order to facilitate my repairs on my TX, I'm happy that it ended.
I don't ask for any payback of course this is all free for you get !
<shameless plug>
I just want to add that to this day I've got a near complete TX516 with 3 missing modules to complete my TX816 so if you got working or defective TF1 units that you'll be ready to spare I'll be happy to talk with you about them ! I fix electronic consoles and music gear so dead units won't be a to much of a problem.
</shameless plug>
Anyway have a nice day and keep the spirit of the FM alive ! Long live Yamaha FM !
