FEATURES
GENERAL. The No. 530 Receivers are nine tube,
three gang, three range receivers, designed for the
reception of Amplitude Modulated stations. The No.
535 Receivers are fifteen tube receivers of the very
latest design, providing reception of both Amplitude
and Frequency Modulated stations. The "Armstrong
Wide-Swing Frequency Modulation System" used in
this receiver is outstanding in that substantially
static-free reception is obtained, plus a degree of high
fidelity which has heretofore been unobtainable in
any radio system.
Six button automatic tuning is provided in these re¬
ceivers, so that six favorite stations may be set up.
Separate continuously variable bass and treble con¬
trols are provided in these chassis.
Provision is made for a record player to be used with
all models not already equipped with phonograph
mechanism without additional wiring.
The No. 530-PL Receiver is equipped with a record
player using a crystal pick-up in conjunction with a
specially equalized circuit. This record player shifts
and plays the standard 10" or 12" records.
The No. 535-PG, PL and PS Receivers are equipped
with record players using a one-ounce sapphire pick¬
up in conjunction with specially equalized circuits.
This type of pick-up eliminates the frequent changing
of needles and reduces record wear to a minimum.
This record player shifts and plays the standard 10"
or 12" records. The records may be intermixed on the
No. 535-PG and PS Receivers.
A loop antenna is provided in these receivers so that
no antenna and ground connection whatsoever is re¬
quired. However, antenna and ground terminals are
provided on the chassis so that an external antenna
may be used for improved reception if desired.
PHONOGRAPH OPERATION. A jack is provided on
the back of the chassis of all receivers not already
equipped with a phonograph mechanism, into which
a record player may be plugged, and a push button is
provided on the front of the receiver for switching
from "Radio" to "Phonograph".
ACCESSORIES
ANTENNA. The built-in loop antenna provided in
these receivers will give satisfactory operation in most
locations. However, for improved reception, a Strom-
berg-Carlson All-Wave Antenna is recommended.
These antenna are supplied in kits containing all the
necessary parts for mounting and installation, and
are designed especially for use with all Stromberg-
Carlson receivers.
HEADSET ATTACHMENT. Headphones can be very
simply attached to this receiver. Ask for Pc-2830'3
Headset Package Assembly, which comes complete
with headphones and installation instructions.

CARE OF THE CABINET. The finish of Stromberg-
Carlson cabinets should be protected by using Strom-
berg-Carlson cabinet polish regularly. It is available
in pint cans designated as Pe-28601.
Nicks and scratches of most kinds can be repaired
quickly and easily by proper use of the Pc-26962
Touch-up Kit. Complete instructions are provided
with each kit.
ADJUSTING THE DIAL LAMP. To obtain the proper
illumination of the dial, slide the two dial lamp sock¬
ets on their mounting brackets to the position where
maximum illumination of the dial is obtained.
