REVIEW
H
a—Two-pivoted tone-control leaves at the mouth of
the amplifying chamber permit modifying the
volume of tone as desired.
b—The cover encloses the scientifically shaped ampli-
fying chamber (or horn) which permits the full
and natural development of the sound-waves (as
in the big cabinet Grafonolas) from the neck of
the tone-arm to the mouth of the horn.
c— An escutcheon at this point fits over the motsr
pinion and secures the turntable against rattle or
damage during transportation.
d—The standard Columbia bayonet-joint tone-arm
conveys the sound-waves directly into the amplify-
ing chamber in a continuously widening channel
without obstruction or the necessity of employing
special turns or adjustments to suit this type of
a phonograph.
g—The position of the winding spindle gives the
crank a wide swing which permits easy and safe
winding of motor.
h— Complete exterior is covered with the best grade
of heavy black Fabrikoid.
i— Heavy nickeled corner protectors give strength,
withstand abuse and save scratching of furniture.
/—The inside is finished in highly polished Red Ma-
hogany which, with the highly polished nickel parts
and black Fabrikoid exterior, makes this instru-
ment very attractive in the playing position.
k—Tone-arm and improved standard Columbia re-
producer swing back without adjustment and are
safely positioned by a spring for carrying.
e—Needle cup covers seal needle cups when cover
is lowered for carrying. Wmt:
/—Winding crank is conveniently positioned here for
transportation.
/—Three shaped nickel neecMvWps (one for used
needles) prevent aggravating forgetfulness.
m—Ingenious safety catch permits dust-proof closing
of cover.
