• Welcome to the Pipe Organ Forum! This is a part of the open community Magle International Music Forums focused on pipe organs (also known as "church organs"), organists, organ music and related topics.

    This forum is intended to be a friendly place where technically advanced organists and beginners (or even non-organists) can feel comfortable having discussions and asking questions. We learn by reading and asking questions, and it is hoped that the beginners (or non-organists) will feel free to ask even the simplest questions, and that the more advanced organists will patiently answer these questions. On the other hand, we encourage complex, technical discussions of technique, music, organ-building, etc. The opinions and observations of a diverse group of people from around the world should prove to be interesting and stimulating to all of us.

    As pipe organ discussions can sometimes become lively, it should be pointed out that this is an open forum. Statements made here are the opinion of the poster, and not necessarily that of the forum itself, its administrator, or its moderators.

Ahlborn Hymnus 350 mechanical keyboard problem


New member
Hi everybody,
I recently unscrew the rear panel of a keyboard of my Ahlborn Hymnus 350 organ. I thought there were there the contacts of the keys, but not. In fact, this long metallic rule (see attached picture, it's the rule with 9 circular screws) seems to be a huge "screw" keeping the keys in place. Unfortunately, I'm not able to put it back correctly : whatever I try, half of the keys stay stucked and can not move anymore :(

Does anybody have an idea of how to do the job ?

Thanks a lot by advance for your answer.



Hi...Is this organ, an European (German) based instrument. This organ hopes to have custom consoles.

You might need to contact Klaus Reetze in Germany or Ahlborn organs in Italy.

I have never observed consoles like those in the image, yet realize they had an Italy organization make wooden consoles, and later they utilized wood Fatar consoles.
