Residence Organ, 
 - Description and History from John Dolan


The organ is based on M. P. Möller Opus 6599, originally installed in Sacred Heart 
Roman Catholic Church, Charleston, South Carolina.  The original organ was M. P. Möller 
Opus 6599 and has been added to with other Möller chests and pipes from Opus 7977 
(from Philadelphia), chests from M.P. Möller Opus 4202, home built direct electric
chests. Additional pipe work from Möller Opus 1543, from (believed to be) Hook & 
Hastings 4/320, and Wurlitzer Opus 8995.

Team that removed the organ from Charleston, SC was: Mary Ann Quarry,  
Jay Cummings, Branson Frye, Ken Warren, Marc Cheban, and John Dolan.
Team that removed the M.P. Möller Opus 7977 from Philadelphia was: Mary Ann Quarry,

Currently using the console from the M. P. Möller Opus 6599 that we removed from 
Sacred Heart RC Church.  The console has been revised to accommodate additional 
stops. Have only combination action for the stops controlled from the original 
mechanical system in Möller’s console-Opus 6599.   Added magnetic reed switches 
from Peterson to the pedal board and using Peterson drivers for the pedal ranks. 

The console rests on a movable platform. 

The pipe chamber (17’ x 30’ x 11.5’ high) is located in the basement under the 
entire music room located on ground floor of residence.  The sound travels up from 
the basement to the music room through a sound chute having a 4’ x 8’ cross-sectional 
area.  The sound chute creates a 4’x 8’ hole in the music room’s floor which is 
hidden by the original Opus 6599’s white oak façade containing 14 façade metal flue 
pipes.  Eight shades with 8 pneumatic motors are mounted on the sound chute in the 
pipe chamber.  The entire organ is under expression.

The blower is by Kinetic: 1-HP single phase, 240 V motor 650 CFM blower with 10"dia 
conduit into pipe chamber then splits into two 8" dia conduits.
