Condition of the organ

According to our report of October 2007, we found the pipework in good conditions. There was no woodworm in the woodwork. In the main, the technical layout worked very well. A large number of failures in the console and the electricity supply serving the organ gave grounds for complaint. The latter could not be guaranteed to meet the safety requirements for low voltage equipment.

The reservoir bellows and windtrunks are no longer air tight due to the chapped leather. Various small bellows and membranes made of leather that are important for control of the sound have to be replaced. The leather of the drawstop bellows, which switch the individual stops on and off, is also defective. Worn leather causes loss of air tightness and thereby to an imprecise reaction of the sounds and stops, or to leaks and detuning.

Restoration

The majority of restoration work will be carried out from November 2019, when restoration of the church has been completed. It will be based on a comprehensive inspection of all the organ parts. To this end the organ will be taken apart. The individual parts will be cleaned and repaired. When the organ is being reassembled the whole mechanics will once more be readjusted to the highest possible standard. Wherever necessary, our experts will replace the leather to parts of the key action, the stop action and the bellows.

Windchests, wind system and pipework will be restored and retained. The pipework will then be revoiced according to the original parameters. The external appearance of both organ bodies will remain unchanged.

Additions

The whole of the electrical controls will be refitted. A console with four manuals will allow the choir organ, which was installed in 1960, to be played independently. The console will be state of the art and improve the ergonomics for organists. The planning and design of the console will be undertaken by Orgelbau Kuhn.

The new Vario capture system will be controlled via a touch screen, having a nigh on limitless number of sound combinations that can be stored, and facilitating clearly structured storage thanks to designation, sorting and search functions. Other innovations, such as free couplers, a transposing keyboard, recording facility and MIDI interface, to name just a few, open up further musical possibilities to organists.

An additional windchest will be placed on the west side of the gallery. Until now, the Principal 16' stop in Great did not have its own pipes for the lowest octave. These twelve pipes will be supplemented on the new windchest. The Subbass 16' stop will also be moved there and extended to an Untersatz 32' stop (twelve pipes C-H, wood, stopped). The room consequently freed up at the previous location of the Subbass 16' stop will be used for a new Violon 8' stop.
