The general renovation of the organ comprised the following tasks:
Cleaning the entire organ including the exchange and renewal of all membranes of the conical windchests as well as the pockets in the windchests dating back to 1960. The entire wind section was thoroughly renovated, we installed a new blower unit, and all bellows were equipped with new leather parts and sleeves. We also exchanged the magnetic levers of the windchest relays.
Anotther big task was the renovation of the four-manual keyboard table. All contacts of the playing apparatus were replaced with new silver contacts. We installed a large tuning combination capture combination system including disc drive to save different registering patterns into the register section.
We did not change the historic disposition of the keyboard-table easel, we only connected the register keys to the register-setting magnets.
Also, the function of the free combination switches remained intact, so now registers may be pulled either via the new capture combination system or else the old switch combination. In agreement with the responsible persons in the parish, the tune level was raised from 435 to 440 Hertz to allow joint music between organ and orchestra or solo instruments.
Our voicing experts Mr. P. Akroud and Mr. J. Campbell effected some subtle modifications in the total sound.
We soldered 56 new cover flaps onto the very unstable vox humana and eased the tuning spring, as the tuning would not hold with this register. Modifying the cuts, the intonation was changed for all pipes with "Principal 16’ " in the organ front in order to achieve a better response and basic tuning fundamental sound. At the quintadena, too, we modified the cuts and soldered flanges to the metal pipes to achieve a stately sound.
Octave 8’, tubular flute 4’ and octave 4’ were also intonated in a more stately fashion, part of the pipes was shifted by half a tone.
In the IIIrd manual keyboard, registers Principal 8’, Stillgedackt 8’, Schwegel, third, Nasard and third cymbel were shifted and changed in their intonation. In the pedal section, the registers Nonen cymbel, block flute 2’, trumpette harm. and mixture were shifted and completely changed in their intonation.
The necessary or requested intonation changes mainly resulted from modifications of the instrument during the neo-baroque style era of the 1960’s.
