(PEERLESS TRANSFORMER)
$19.75
This latest and most advanced Ileathkit hi -fi
amplifier has all the extras so important to the
super -critical listener. Featuring KT-titi tubes,
special Peerless output transformer, and new circuit
design, it offers brilliant performance by any
standard.
Bass response is extended more than a full
octave below other Ileathkit Williamson circuits,
along with higher power output, reduced inter -
modulation and harmonic distortion, letter phase
shift characteristics mid extended high frequency
response. A new type ',showing circuit makes
balancing easier, and at the same time permits a
closer "dynamic" balance between tunes.
Aside from these outstanding engineering features, the W -5 manifests new physical design as well. A protective cover fits over
all above- chassis components, forming a most attractive assembly-suitable for mounting in or out of a cabinet. All connectors are
brought out to the front chassis apron for convenience of connection.
Model W-5M cotmists of main amplifier and power supply on single chassis with protective cover. Shpg. Wt. 31 Ile.

SIR:
... I went to the Toronto Audio Show
and enjoyed it very much with the exception
of the following which appeared
right in the middle of the
official catalogue under the heading
"How to Choose the Components for
Your Home High -Fidelity Music System."
"The Recording Companies are constantly
refining their product; certain
selected recordings leave little to be
desired in technical and artistic perfection.
On the other hand, the serious
listener must learn to discount defects
in Swot pressings occasioned by deformed
stompers used in processing
the recoral, scratches, and ticks and
pop.' incident to impurities in the record
bare" [Mr. Shiner's italics).
Here is one serious listener who
refuses to do any such thing, and regards
it as slightly ridiculous that he
should be advised to put up with a
pressing from a deformed stamper for
which he is expected to pay $5.95

SIR:
Having completed reading the June
issue in detail and the Posner -Fink
article, "Baha, Betofen, and Bramsu" in
particular, I am now compelled to
write. The article tends to mislead
and, worse, omit, and needs be clarified
by an astute, traveler -audiophile:
myself. Let me first qualify by stating
that I am recently returned from a
seven -year residence in Japan as an
electronics engineer who, hobby -wise,
rigorously pursued the art and science
of high fidelity.
Now Messrs. Posner and Fink imply
that hi -fi is sweeping the country or
has swept the country recently like
"seasonal typhoons" and cite as an example
the emporium known as Confectionery
West. In mid -195o I sat
contentedly in Confectionery West
sipping coffee, eating an hors d'oeuvre
sized strawberry shortcake, and listening
to Brahms's Fourth, which casr.tded
majestically from a modified
