Below is a partial list of restoration milestones. This page is still under construction and is by no means a complete list, nor does it cover numberless tunings and specific repairs, or the gifts of time and talent of many people. The material is presented in reverse chronological order to highlight the most recent accomplishments
2024
Rebuilt Tuned Gongs, which have been moved to the Sixth Floor, come on line for the first time in about 15 years. They were formerly in front of the Main Pedal Division, a space which is to be occupied by a new Contra Trombone 32′ extension. Front two chests of the Solo Division are re-actioned. Restoration details are covered in detail in the Friends of the Wanamaker Organ newsletter The Stentor, sent free to those who join and financially support the Friends.
2023
Restoration is completed on back chest of Solo and two mixtures at top of chamber, with them coming back on line together with numerous reeds that had been restored during the fall. Solo offset chamber cleaned and varnished, with 16′ Tuba and 16′ Double Trumpet offsets (49 notes) restored and returned to operation the next year. Main Pedal reservoir restored and all pneumatics replaced. Pedal 32′ Metal Open Diapason restoration completed with new winding. Great Unenclosed Trumpet restored as a memorial to Karl Eichner by his wife Janice. All pipes on the rear chest of Great Unenclosed restored, and new rear sound-reflector panels of MDF are crafted and installed. The Theodore Presser Foundation funds additional significant upgrades to our audiovisual studio. Macy’s financially supports new microphone rigging among other significant organ projects, as in past years. Work is being done on a new blower panel that enables various blowers to be turned off or on individually.
2022
Numerous restoration projects continue. Solo division pneumatics for the back two chests are returned, Solo reservoir is rebuilt, Solo stop actions are readied and pipes await replacement. Numerous Fleming pneumatics renewed by Dr. Charles Bower. The Theodore Presser Foundation funds significant upgrades to our audiovisual studio.

Friends member David Wanamaker funds the restoration of the bronze Eagle by Evergreene Architectural Arts.
Work is completed on the Pedal Grand Mutation X mixture, a huge harmonic stop that has the ensemble effect of a 32′ Contra Bombarde. The massive chest also includes a Cello and two Tibias (8′ and 4′) and two Fagottos, 16′ and 4′. All of the pipes are cleaned and regulated and the area around them is acoustically enhanced with reverberant coatings. A new rubbercloth gasket covers the top of the chest below the pipes. Also the design of the primary was corrected with the insertion of stronger electro-magnets and smaller first-stage primary pneumatics resulting in a swift playing action on 11″ wind.
The Giant Gong on the seventh floor is winded and readied to be placed in service following a period of testing and refinement of its custom-designed striker.
Pedal offsets are returned to playability through new winding and through wiring trouble-shooting.
Huge new wind lines are run from the Main Blower room to the Main Organ in the ceiling area above the sealed off hallway known as Frosty Central. The old galvanized lines had rotted out through mists blown through them to humidify the windlines and chests. As a result the Organ is much quieter.
The Great Chorus division is cleaned of plaster dust resulting from the Wanamaker Building lobby re-design.
Hundreds of leather pneumatics are recovered in preparation for re-installation in the Solo division. Old gasketing is removed from the bottom of the chest so that restored bottomboards with gasketing on them can be put back in place, sealing the channels.
2020

As part of the project, the Combination Action was expaned to 1000 levels, and a sequencer was installed to allow any piston to advance the settings to the next higher General Piston number. Opus 2 works by monitoring which stops or keys are on or off and sending the information digitally to receptors inside the organ, which interpret the information and send current through the appropriate wires to the magnets.
