They,
there-

siven
any hish
quality
fumitu.e. The linish is hand
rubbed. For dusting we sugsest a cl€an Boft cloth. To
remove finserprints or film, the clotb

be
slisht-
ly dampened with waier to which
a littl€
very mild
soap has been added.

TUNING
THE ORGAN
The Gulbransen Transistor O.san Model E
is an all
electronic organ employinS
a TraNistor Oscjllaror
tone
senerating
system- The
tone
senerator
employs
84
transistors, on€ for each
of the
84
available
pitches.
The
Transistor Oscillai,or
circuit is a very stable one
and
your
orsan should not .equire
hmins.
AMPIIFIER
AND SPEAKER
SYSTEM
The
tones
generat€d
by the
tone
generator
arc
ampli-
fied by a hish
power
amplifi€..
This arnplifier
is
mo'rnt€d on the k€ybed behind the
playing
keys
The output
fron the amplifier is converted
inlo
sound by a loud speake. contained
jn
a specially
desiSned loud speaker enclosure
at the right end oI
CONIROI.
OF MAXIMU/VI
VOTUME
Wher€ the organ is to be u8ed in a small
room,
it
may be
preferable
to limit the maximm
volume to
a somewhat lower level to
utiliz€
the
full rdse of
the
expression
pedal
and
y€t
never
make
the organ
ex-
cessively loud
for
it€ environment.
A Potentiometer
marked
"Max
Vol" is
adjusiable
fmm the top of tbe
amplilier chsssis and can bF set lo limit
rhc maximum
volMe. This is a very Eimple adjustment and
one
{hich
your
deate.
will be
stad
to make for
you.
CAUTION: N€ver tum ihe volume control clockwise
so far as to cause distoriion when
playins
full cho.ds
with the expression
pedal
all the
way
open
as con
tinuous operation in an overloaded condition can
cause damas€ to the loud sp€aker.
FREQUENCY RESPONSE
In
th€ Cutbransen or8an the tone
senerator,
the amp-
lifier, and the loud sp€aker system all cooperate io
produce
mu3jc of a highly distinctive character.
In
order to obtain this specializ€d
performance
the fre'
quency
response and
othe.
amplilier
characteristics
are intentionally different from thos€ of systems in-
tended
for
playing phonogmph
records, tapes, and
similar types of entertainment
haterial
and
for
these
reasons the amplifi€r and speaker system of the
organ caimot be used for these
purposes.
