Special notice: This organ is for sale, contact Tom Hamilton for more information.
This all electronic organ was built jointly by the Roger Colby Company of
Johnson City Tennessee (console) and the Classic Organ Company of
Toronto, Ontario Canada (electronics). The specifications called for it to
look like and sound like (in as much as possible) the 4-22 Robert Morton
in the Ohio Theater, Columbus, Ohio. Colby took extensive
measurements and photographs of the console, and Classic recorded the
tonal qualities and levels of the various ranks..
The organ was originally installed in late 1986 but as with any large
custom installation the bugs were not all worked out until early 1987.
Since then there have been improvements and additions such as when
the Ohio theater added a number of ranks, I had Classic add the same
stops to keep the two instruments similar.
Other than some dirty contacts on occasion, an amplifier that went noisy
and a control board that went bad, there has been no other maintenance
to the organ. Concerning the above, the amplifier and defective board
were replaced by Classic at no charge. During the last ten years I have
cleaned the contacts myself once.
Except for the speakers, everything is housed in the console. There are
13 external speaker enclosures. Twelve of them are 30" wide, 18" high
and 14" deep and contain three speakers each. The 14th cabinet is 18" x
18" x 24" high and contains a dual voice coil woofer. The twelve regular
speakers are by-amped to separate the bass and treble. Total there are 37
speakers in 13 cabinets, 24 channels and over 2,000 watts of power. I
have the speakers mounted on a shelf centered high in the room, half
facing right and half facing left and projecting into a peaked ceiling to
give the illusion of the sound coming from a right and left chamber.
