Philco Model 38-4XX Console Radio (1938)
Philco 38-4 (1938)
The Philco model 38-4XX was introduced in the summer of 1937 as one of
Philco's
"No Squat, No Stoop, No Squint" style radios offered for the 1938
model year. The initial list price was $100 in Eastern and Central regions.

The set's "
inclined control panel" and "cone-centric tuning dial" were touted
as offering the consumer new levels of comfort in operating a radio. However
only a handful of models ever used this dial and by the following season, in
spite of them having sold quite well, the dial was discontinued. Philco's other
automatic tuning dial was also discontinued after this season too.

Below are some extracts from original Philco advertising for the model 4XX.

Automatic Features Join Inclined Control Board as Convenience Predominates

Philco, having given radio reception in the home the inclined sounding board which brought every note up to ear level, now brings the inclined control
panel to dialers with the introduction of its new series of Double X models for 1938.

It is this new feature combined with redesigned and highly improved dials and combined also with Philco's new automatic tuning, which gives rise to
the new Philco slogans "No Squat, No Stoop, No Squint".

The new series of radios have been designed with the comfort and convenience of the listener given first consideration, Philco announces. The result
is that whether the listener be seated or standing, or gliding by the radio in step with some dance number, a new station may be instantaneously and
accurately tuned in with no more effort than it takes to reach one's hand toward the set.

Thus, says Philco, the inclined control panel does for the listener's eyes and back what the inclined sounding board did for his ears.

Philco's new automatic tuning system for the Double X models provides for dialing a station in a simplified telephone manner - just once and click,
there it is. Counterbalanced magnetic tuning assures positive accuracy automatically and an accuracy that will keep the program constantly and
properly tuned.

Models from the Double X series are available in several different reception range combinations for reception of  police, foreign, amateur, and aviation
short wave and both domestic and foreign long wave broadcast.

With the introduction of its complete 1938 line, Philco again makes available a radio model for every purse and for every purpose, including battery
models for the farm homes in unelectrified areas, automobile radios and special service receivers providing coverage for US weather stations, foreign
long wave stations and ultra short-wave broadcasts.

A wide range of table models is included in the complete line with both short-wave and regular broadcasts covered in them.

Philco also presents a delightful model which it calls a "sit downer". It is a chairside model equipped with Philco Cone Centric automatic tuning, which
provides all the ease an convenience of being able to tune favorite stations without getting up out the easy chair.

A table model endowed with Philco automatic tuning also is included among models singled out for special attention. Both models are equipped for
short wave as well as broadcast reception.

The Philco Balanced Superheterodyne circuit, raised to new standards of performance by the engineers this year, is utilized in all the new Philco
models. Some of the other features of all new models are metal shielded circuits and tubes, patented rubber mounting for condensers and built-in
interference filters.

Note: the above copy makes reference to Philco's Magnetic Tuning system, available on some of the season's Double-X models, such as my 38-116XX.
This is an electronic technique which the 38-4XX, along with other sets using the cone-centric tuning dial, did not utilize.
