Zenith 10-S-153 Console Radio (1937)
The technical details of the 10S153's type 1004 chassis, along
with a link to the schematic, can be found on my
10S130 page, so
I won't duplicate them here.

The 10S153 Acoustic Adapter Conundrum

If the original Zenith service literature is to be believed, all 10S153
consoles came from the factory fitted with loudspeaker part
#49-156, which has no Acoustic Adapter (AA) attachment. How-
ever, this information appears incomplete, as there are numerous
examples of this model around today which incorporate the alter-
nate loudspeaker (part #49-147) carrying the adapter and assoc-
iated mounting hardware.

In late 2006 I initiated an informal survey on this subject at the
Forums. Some respondents reported their models as using part #
49-147 (with the adapter) while others reported their's as using
part #49-156 (without). I myself have two of these radios, both with
adapters. A secondary finding was that the serial numbers of
models having/not having adapters do not appear to correspond
to particular batches of 10S153 chassis production, though to be
fair, the sample size was small.

To see if I could shed any further light on this matter I conducted a
search of numerous 1936/37 newspapers, looking for Zenith ad-
vertising featuring the 10S153. I did in fact come across many
instances, spread throughout the model year, where the Acoustic
Adapter was listed explicitly as a feature of the 10S153. However,
there were almost as many ads that did not or left the matter
vague. A selection from these ads is presented to the right and
lower on this page, together with highlights extracted from the var-
ious ads. Were the numerous ads claiming the 10-S-153 to offer
the device all wrong?

Based on the evidence, it seems highly likely that  the 10S153
models did in fact come from the factory both with and without the
Acoustic Adapter. I therefore feel justified in including it on my list
of 10S153 features - shown above.

Zenith Model 10-S-153 (10S153) Console Radio (1937)
"For best tonal effect, a radio must be
balanced to the room. Or the room to the
radio. Obviously, the room cannot be
balanced to the radio - so, Zenith has the
Acoustic Adapter - a "tone balancer" to insure
sharp, crisp, clear reproduction in any room.
Once you've heard a Zenith in your home,
you'll never be without it."
The Zenith 10S153 is an attractive mid-sized console introduced in
June of 1936 for the 1937 model year. The introductory price was
$99.95 in the East ($104.95 West of the Rockies) for the basic wal-
nut cabinet. The radio features the "squared-circle" version of the
big black dial, having controls at each corner and lower center.
Other features of the 10S153, in words borrowed from Zenith adv-
ertising sources, include:-
  • Big Black Improved Dial - Zenith's most imitated feature
    again improved.
  • Telltale Controls  - easy to read, easy to tune. You don't
    need glasses. Everything as simple  as a-b-c.
  • Lightning Station Finder - Gives you the exclusive Emde
    Spinner-Tuning method. Gets any station with the flick of a
  • Split-Second Relocator - for quick, reliable and accurate
    short-wave tuning. A patented Zenith feature imitated in    
    looks but not in deeds.
  • The radio with the overtone amplifier - should not be
    confused with "trick" tone modifiers
  • Voice, music, high fidelity control - a feature you must  
  • Zenith Acoustic Adapter - being heralded as radio's most
    outstanding tone adjustment
  • Target Tuning - Zenith's simple, accurate tuning method.
  • Metaglas tubes
  • Triple Filtering
  • Choice of smart finishes (see below right)
Zenith 10S153.. a quality radio at a bargain price.
Elegant... with a suggestion of massiveness in its simplicity.
