I am very interested in replicating the CDQ1-IHF-LP / ERRMO-EU for personal use.
Can you please post the circuit diagram for it?

....In this case, it would actually be much less effort and considerably less risky
to simply procure a finished (used) device from series production with a proven circuit board....

....And here is my private archive copy CDQ1-IHF-LP with serial number #100 ....

This NOS unit now has a new home with a copy processor collector in Romania 
.

Thank you, Axel!
