The console restoration is complete.  Front view of console showing new pistons, new stop tabs, control panel, MIDI sequencer and solid state components below.



Close up of the back of the stop action magnets after the wiring harness has been installed.

This is the rear view of the console.  Combination action (memory) circuit boards are at the bottom. 


All the stop tabs have been installed in the console and most of the console wiring is complete.

Here are all the stop tabs mounted to the stop action magnets (SAMs).  The SAMs are the machines which move the stop tabs when the organist presses a preset button.

The engraving has FINALLY arrived after a long wait.  These are the new stop tabs for the console.


The rest of the console electrical system.  These circuit boards are the memory system (combination action) and there is at least one for each division of the organ.


Part of the console electrical system.  The large circuit board is the main CPU and the smaller ones are the inputs for the keys and stops.


The swell relay panel


Most of the past week has been spent making up the various wiring harnesses for the console.



New keyslips are now being made.  These are the strips of wood which hold the preset pistons that are

to be located under each keyboard.



Manual keyboards have been completely restored including the installation of new springs, regulating screws, felts, and replacement of broken ivory.  The optical keyswitches have also been installed under the keys.



Finish has been applied to the new console interior.


New console interior complete

New stop jambs and coupler rail of Oak are complete and ready for stain.  The new interior of the console provides sufficient space for about 107 new stop tabs.
