Needle Wear
cessive record wear. It takes a skilled
craftsman to shape the patented elliptical
point and fashion a perfect radius which is
so important. For perfect performance it is
best to replace the worn needle with a
new one after it has played 2000 records . ♦

Only through the use of the microphoto
can an operator fully appreciate the delicate
yet sturdy construction of the new Standard
Elliptical Permo Point Needle. Hundreds
of operators have found, during the past
eleven years, how indispensable this modern
phonograph needle is to perfect automatic
phonograph reproduction.

of a human hair. This is possible because
the precious metal point material is ex-
tremely fine grained and smooth and creates
a self-lubricating polishing action in the
groove rather than an abrasive action.
Many operators prudently anticipate the
time when the needle will no longer give
efficien t service and make replacements,
thereby protecting themselves against ex-
pensive service calls and needless wear on
records. This is done by checking the num-
ber of plays as recorded on the meter, and
inspection of the needle point with their
Magnifiers.
In the past a few operators have tried
resharpening used needles because they
could see the apparent excess of P'recious
metal on the poin t. This has always proved
to be false economy as it leads to poor
reproduction, extra service calls and ex-

George Hall possesses a record for
the longest musical run on Broadway,
having played at the Taft Hotel for
more than six years. In the matter of
broadcasting, he . has been allotted
more time during this period than any
other musical attraction heard over
CBS. Hall was born in Brooklyn. His
father was associated, as violinist, with
the eminent Walter Damrosch. Conse-
quently Hall was educated for a musi-
cal career. After many arduous years
of study, he .became first violinist for
Victor Herbert and relishes many happy
mem ories in this relationship. Consid-
ered the most unaffected bandsman
along Broadway, Hall has always made
it a stern policy to employ musicians
who could legitimately interpret his ar-
rangements. In the matter of arrange-
ments the first requisite was embellish-
ing the melody with modern harmonic
designs.

A man and his wile were suffering
from seasickness, while their young son
became more rowdy by the minute.
Finally the mother mustered courage
and voice enough to say:
"John, I wish you would speak to
Willie."
The father, unable to lift his head,
said feebly:
"Hello, Willie."

By comparing illustrations one and two,
it may be observed that the elliptical point
is twice as long as it is wide. This gives the
practical feature of having two points on
one needle. The even wear that is illustrated
in view number three is made possible by
the construction of the needle with these
two bearing surfaces, guaranteeing a full
life before the Perino Point is discarded.
Music operators make use of this desirable
feature by reversing the position of the
needle point in the pickup one half turn
every three to four hundred records.
That operators are sometimes confused
by the apparent excess or surplus of preci-
ous metal point material remaining after
the Permo Point has played over 2000
records, indicates the perfect construction
and even wear of this modern needle. Oper-
ators must remember that it is necessary to
have a minimum amount of point bearing
surface in the record groove at all times for
fidelity reproduction.
It is interesting to note that the Permo
Point needle, in 2000 plays, shortens, in
overall length, the approximate thickness
