I want to have a schematic from this FET RIAA Preamp for removing unwanted AM reception:
https://luckyx02.de/data/documents/Aikido_Phono_Prospekt_Mail-1.pdf
Der Aikido von H.-U. Otto - Lucky's Hornpage
from the MC head amp (Pre-Pre) therefore there is to find a schematic here - go to the seventh circuit under
Aikido Tube Amplifiers
Even from the tube-version of this FET RIAA preamp there are the schematics - go to
Aikido PH-2 Phono Stage
Aikido All in One.pdf - Tube CAD Journal
https://de.scribd.com/document/150411742/Aikido-All-One

Thank you for upload schematics from oTTo's jFET version like to see in the attached images

Since you have the pictures of both sides of the PCB it is not that had to make a drawing of just the first stage. Add an input filter to stop AM reception that does not interfere with the device its qualities and you are done. Yeah those old fashioned input filters, no one seems to need them these days 
It was a long time ago I was busy with phono but I guess ferrite beads in the signal inputs could also be sufficient. A 100 pF ceramic disc type cap for each inputs GND to chassis might also help in case AM reception is coming via the screen of the cables. Do you use the GND screw as mounted at the back of the device?
And eh pssst... that is a switcher for PSU....

anywhere a schematic for upload of this units under
https://luckyx02.de/data/documents/Aikido_Phono_Prospekt_Mail-1.pdf ??
according the circuit description schematic looks to those under
http://diyaudioprojects.com/Solid/JFET-Phono-Preamplifier-Kit/diy-jfet-riaa-phono-preamp.html
but with additional buffer-jFET like here
https://phonoclone.com/diy-pho6.html
an complete other approach (here from Renardson Audio) is the use of NFB RIAA network

last URL is dead - check out the advice under

go for the phono2 to the URL in post #1 under
