As usual, I went to the Riders books first, and here it is:
- the schematic is in Vol I
- The chassis bottom photograph is in Vol II
- And the alignment procedure is in Vol VIII

So, I went to Nostalgiaair and opend the scans, that are consolidated in one PDF file.
Also there is the issue of the speaker.
I have a spare 20 speaker, which is fairly close. The FC is 3.1K vs 3.4K, and the pin-out pf the plug is the same, so for the purpose of the alignment I might be using that one.

Also, someone who repaired (or attempted to, as I am not sure it would work after this repair) miswired at least one place.
