Hi gemlady,
I own a Celebrity 871. If you send me a PM with your email address I can provide you with scans of my owner’s manual and/or service manual. The owners manual has a good selection of registration examples. As Andy said, there is no pitch tuning possible on the organ voicing with the exception of the Moog Synthesizer. The Synth has a slider that allows you to tune it to the pitch of the organ. However, sometimes because of component ageing or other reasons the pitch may be perfect at a certain note but drift out of tune going further up or down the keys. This can be corrected by playing with three trim pots located on the Moog circuit board mounted on the underside of the organ lid.
I would recommend that you first get the owners manual and learn what all the controls and stops are supposed to do. Once you understand their functions you will be able to assess if the organ needs repair. Controls and Stops of organs that have been idle for long periods may not function properly until they have been used repeatedly.
Good luck,
Skippy
