Thanks for mentioning me, Peter!
The BeoCord 5000 is truly an amazing deck, unfortunately so very complicated that they are horrible to work with if not working! One peek inside makes it sure that it's all-B&O - but when the deck works they are a delight to use (I have one that almost works, it plays but won't record - still I love it).
The schematics diagram will follow - I will scan and send it tomorrow.
My thanks go to beaker for the manuals!
