Hey all,
I've uploaded schematics & service manual PDF I found on the 'Beaulieu Users Group' on FB, posted by Adrian Cousins.
I have edited out the pages that were in non-english.
Link: https://anonymshare.com/mz0D/beaulieu-r16-service-and-repair-manual-eng.pdf (I've used anonymshare bc it claims to have a non-expiry link).
I've attached a photo from that PDF.
I'll also leave here the user's manual for the R16 automatic, if that helps to: http://www.vintagecameras.fr/images/MonSite/BEAULIEU/R16_Electric/_Doc/Beaulieu_R16-Electric_Manual_en_Revu.pdf
Hope this helps!!
