Thursday Nov 12th at the OB

Just a quick update.

Gerry took the bottoms off the string and celeste chests and checked the magnets and for cold or chrystalized solder joints. Two magnets were replaced and a number of cold joints repaired. One bolt anchor was replaced as the bolt was cross threaded, and the anchor is now glued in place with epoxy. Notes that were cyphering had the magnet discs checked for dirt.
 
Ross stapled up the wires to the console in the corner, and will paint them green next trip. He also gooped up numerous holes in the drywall between the chambers, and in the stair well. This should help keep dirt out of the chambers. Shortly we can vacuum the entire organ.
 
Jack worked on the keyboards. It is pointless to try and tune the organ, or search for dead notes without reliable keyboards. The 8 ft E of the solo keyboard had a bit of rubbery yellow dirt on the end of the magnet, once this was removed all notes worked. The orchestral keyboard coincidentally also had an inoperative 8 ft E. This turned out to be a dead Hall effect pickup IC, it will have to be replaced. The key heights, and the trip points on both of these keybaords have been adjusted.
 
The Accompaniment keyboard was turning on all 12 notes of the bottom octave whenever any of these keys was pressed. Seems to be related to a cold or no solder joint on the pickup for the B key. Jack tried to repair it but the thru hole plating seems to be broken. The keyboard is here at my shop and I will take it to Dave next week. We also have one note in the pedals that needs adjusting. These wood screw adjusters keep working their way loose, maybe we will replace them with bolts with Nylock nuts.
 
Aside from all that, nothing else to report.
 
Salut
 
Ross
