A NEW CHROMONICA HOLDER
FOR STRING INSTRUMENTS
Presto-Times calls the attention of the profession,
amateurs and music dealers, to the combination
Chromonica and string- instrument holder manufac-
tured by the Hallbauer Manufacturing Company,
1535 Wellston avenue, St. Louis, Mo., and known
as the "Super Chromonica Holder." The holder
is perfect for playing in combination the Chromonica
with stringed instruments and as the guitar, banjo,
ukulele and other instruments of this class. This
Hallbauer product seems to be the last word in per-
fection of a combination holder that has been ex-
perimented upon for a long time but without really
satisfactory results. The manufacturers claim that
their holder has met the severest criticism of users
everywhere and they know that they have a holder
that will give entire satisfaction.
Although there are harmonica holders on the mar-
ket, it will be found that the Hallbauer Chromonica
holder has many advantages over any other similar
attachment.
Dealers will find this a good seller and well worth
keeping in stock. The manufacturers suggest order-
ing through jobbers of general musical merchandise,
but full particulars will be given upon applying to
the Hallbauer Manufacturing Company, 15,35 Wells-
ton avenue, St. Louis, Mo.
AKRON'S LATEST MUSIC STORE
Ernest E. Smith, for peveral years representative
in Ohio for the Waltham Piano Company at the
Waltham Store, 33 South Howard street, Akron,
Ohio, has established a new music house known as
the Kenmore Music Company, located at the corner
of Boulevard and Florida avenues, Akron, Ohio, with
the Baldwin line as leaders. Mr. Smith intends
to carry on the radio business also and has at the
present time the Majestic as his leader. In a circular
recently sent out announcing his opening he says: "A
piano is worth going miles to buy. A piano in your
home changes the entire atmosphere in your home—
fill that vacant corner in your home now—the family
needs music this winter."
FITZGERALD COMPANY MOVES TO NEW
QUARTERS
The Fitzgerald Music Company of Los Angeles,
Calif., located for many years at 727 South Hill street,
has moved to 645 South Flower street, that city. The
new quarters were remodeled into a most attractive
home for the company, and consist of a two-story
building of thirty feet frontage. The firm makes use
of the entire building, which has been taken over
on a long-term lease. It will be recalled that Charles-
ton Dow some months ago succeeded James T. Fitz-
gerald as president of the company, Mr. Fitzgerald
who founded the business about forty years ago, re-
tiring to private life.
FIRST-CLASS PIANO KEY SERVICE
The attention of music dealers everywhere is called
to the advertisement of the McMackin Piano Service
Company of Des Moines, Iowa, where this concern
gives a special rate for piano key recovering, a price
as low as $5.50. The McMackin Piano Service has
been in this line for many years and is well fitted
in every way to do first-class and satisfactory work.
The McMackin company shops and studios are
equipped with a superior line of machinery and their
workmen and the proprietors are persons of ability
in all kinds of-work relating to piano key work.

MANUFACTURING TO INSURE
HIGH QUALITY
By Ross D. Siragusa, President Transformer Cor-
poration
There is no doubt about it—the industry is vitally
interested in mantel radios. There is nothing essen-
tially new in these sets, but we all admit they are
different. They brought new problems to the radio
dealer, distributor and manufacturer, and when some-
thing different is placed on the market, it is interest-
ing to go over the pros and cons.
The subject has been discussed extensively in print
from a merchandising angle and a few words as to
their manufacture should be appropriate.
Design
The design problems with a mantel type radio are
primarily those of building high quality apparatus at
reasonably low prices in which the utmost in quality
is obtained, both as to the components which go to
make up the set, and the performance of the finished
product.
We have always had inexpensive radio receivers,
but the quality has generally been in accordance with
the price. This season saw a public demand for a
receiver in the low price class, of high quality manu-
facture, of lesser range and power than the larger
receivers but equal quality as to those results which
are obtained.
One example of the problems confronting the de-
sign engineer of the mantel type set, might be cited
in tone quality baffle limits.
It is generally understood for true reproduction
of loud tones, a large baffle is required. This baffle
is supplied in the larger sets by the physical dimen-
sions of the cabinet. -
-
With-a mantel type set, the size of 4he cabinet is
necessarily limited, and of course, so is the baffle
dimensions in the chassis and loudspeaker. This
means that if the present mantel type set were assem-
bled into a larger cabinet, low tones might predom-
inate.
While the public might be pleased to pay one-half
the price of a large set for a mantel type receiver,
they would be pleased to operate that set if it brought
in only half the stations. This, in itself, necessitates
high gain per stage and the higher gain necessary is
obtained by many manufacturers in increasing the
ratio between the tuning condenser for a particular
stage and the r. f. coil for that stage, and is unusually
brought about by a decrease in the capacity of the
condenser tuning that stage.
Theoretically, this answers the purpose, but unfor-
tunately, a good receiver that the public will buy, is
seldom produced entirely on paper in the matter of
its design. For example, if the capacity of the tuning
condenser we have mentioned is decreased, it means
that such capacity as is left in the condenser must
be worked within closer tolerance than would be
the case with the larger condenser.
A uniform sensitivity over the tunable range is de-
sirable in any receiver, fortunately, is more easily
obtained in the mantel type radio than in its big
brother. Amplification of stations operating on high
or low wave lengths is assured in equal degree by
means of compensation. In the r. f. coils, compen-
sation is simpler by virtue of fewer tuned stages,
thereby having less to compensate for. It would be
safe to say that 75 per cent of design problems with
mantel type radios are brought about by very com-
pact assembly; for example, ventilation holes m the
chassis are desirable whereas, in a large set, with
greater space for heat radiation, they would be un-
necessary. The field coil of the dynamic speaker has
openings diametrically opposite, to permit air circu-
lation, and it is good practice to leave one side of the
power transformer unshielded for the same purpose.
It is necessary, of course, that the unshielded side of
the transformer carry only low voltage leads.
THE MIDGET AT LOW SALE PRICE
It would be well to clarify this point by explain-
ing that no one manufactures a perfect anything, and
this is particularly true when we are dealing with
such apparatus as radio variable condensers. They
are manufactured with a certain capacity intended for
each stage. When the condenser is finally assembled,
it will be found that each stage in the variable con-
denser gang departs slightly from the ideal value by
being either greater or smaller in capacity. Radio
reproduction engineers set a limit to the amount by
which any condenser may depart from the ideal value
and term this a plus or minus tolerance.
To give the reader some idea of how closely these
tolerances are held, it might be interesting to know
