  • (Database Manager. June 10, 2011)
  • Updated through online information from Philip J. Fillion.
    The organ is in a deplorable condition due to minimal maintenance, and some unfortunate work. Presently the entire Gallery Swell division is unplayable, since at an unknown time the wind trunk to its windchest was cut to stop ciphers.

    This wind trunk also fed the C# side of the Pedal Principal 16 and all Pedal stops from 8' up (added by Brantley Duddy on new chests next to the old case); thus they no longer play. A variety of action problems have caused a number of dead notes, and the combination action is no longer reliable, failing to both add and cancel stops in every division at various times.

    The shutters to the Chancel Swell no longer function, nor do any stops in the Antiphonal. The electronic 32s continue to operate with some regularity. The Serpent 16' has been returned to its original home in St. Paul's Church, Chestnut Hill. (Database Manager. April 14, 2016)
  • The console is from Austin Op. 1010 (1922), Eastman Theatre, Rochester, New York. (Jeff Scofield. May 27, 2019)
