INSTALLATION AND MAINTENANCE
The organ must be connected to a regulated frequency source of the
voltage and frequency specified on the name plate. If the frequency is
not regulated the pitch of the organ will be irregular.
When a console is set up for operation the anchoring must be loosened so that
the generator will float freely on its spring suspension system. No damage
will result if this is not done, but the console will sound noisy, and the same
is true if the anchoring is loosened but the console is not level. If the console
is to be moved a long distance the anchoring should be tightened during such
moves.
Several different types of anchoring have been employed and instructions for
loosening and tightening the generator in any particular console are given on
the instruction card contained in the bench which accompanied that console.
Each power amplifier has anchoring which should be loosened on installation
and tightened for shipping. If the cabinet has a reverberation unit, it should be
locked before moving the cabinet and the fluid should be removed as instructed
on the card attached to the tone cabinet.
The tone generator is lubricated by putting oil into cups inside the console. It
is recommended that each cup be filled three-fourths full, (1 tablespoon) once
a year, using only the oil recommended for this purpose.
POWER AMPLIFIER
A-l00
A twelve watt amplifier is mounted on the lower shelf of the console. It receives
the signal from the Preamplifier and increases it in power to drive the two 12"
speakers.
D-100
A fifty watt three channel amplifier (bass with reverberation, treble, treble
with reverberation) together with its independent power supply is located on
the lower shelf of the console. It receives the signal from the preamplifier
and furnishes power to drive the 2-12" speakers and 2-8" speakers.
C2-G
These consoles are identical in appearance to the C-2 and C-3 except that a monitor
speaker is located on the lower left hand side. The preamplifier in the C-2G is
designed to operate the monitor speaker. In the C-3G the preamplifier is the same as
in the C-3. A small auxiliary amplifier drives the monitor speaker. In both Models,
B+ voltage from the tone cabinet is required to make the monitor speaker operative.
The HR-40G is identical to the HR-40 except that it is equipped with a standard 6
conductor cable which must be used in conjunction with the C-2G console.
