Hi @sarlagri ,
Here are 2 links for the schematics.
I’ve used the 1st link website before for other schematics with no problems .
The 2nd looks familiar but it was a long time ago but I had no problems downloading it now just to see if there was anything untoward about it but it went OK.

Hopefully one of them will help you.
