8.200 OUTPUT TRANSFORMER

50." 5' PM SPEAKER

LINE VOLTAGE: This receiver is designed for operation on 105-125 Volts,
50-60 Cycles, either Alternating or Direct Current (AC-DC)

POWER CONSUMPTION: 30 Watts.

UNDERWRITER'S LABORATORIES LISTING: This receiver is listed under the
Reexamination Service of the Underwriter's Laboratories as indicated by
the label attached to the cabinet.

TUNING RANGE: Broadcast: 540 to 1650 Kilocycles (180 to 555 meters).
DIAL: The Dial Scale is calibrated in Kilocycles.

TUBES: The tubes used, and their functions, are as follows:

BSS7 R. F. Amplifier IZSQ7 Detector, Avc and Audio Amp.
lZSA7 Converter SULGGT Beam Power Amplifier
6557 I. F. Amplifier GSZSGT Rectifier

MINOR REASONS FOR FAILURE T0 FUNCTION: Defective tubes: defective
Volume Control and On-Oii Switch; line cord reversed on D. C.; defective
line cord plug: or tubes in wrong socket.

ALIGNMENT: Should it become necessary at any time to check the alignment
of this receiver, proceed as follows:

(l) Set the Signal Generator to 455 KC and connect to the grid of the 6SS7 R. F _
Amplifier. or to the Stator Lug on the rear section of the Variable Capacitor.
Connect the Signal Generator Ground Lead to a "-B" point underneath
the chassis. Connect a suitable output meter across the Speaker Voice Coil
Connections. First turn the Volume Control to the maximum position. Turn
the Variable Capacitor to the extreme clockwise position.

(2) Adjust the trimmers located at the top of the first and second I. F. Trans-
formers for maximum output as indicated on the Output Meter.

(3) Loosely couple the Signal Generator lead to the Loop and set to 1650 KC.
(4) With the Variable Capacitor set at the extreme clockwise position, tune
in the 1650 KC signal by means of the Oscillator Trimmer on' the Variable

Capacitor (front section).

(5) Set the Signal Generator to 1500 KC and turn the Tuning Control so that
this frequency is indicated on the dial. Adjust the Antenna Trimmer on
the Variable Capacitor (rear section) for maximum output. No other
adjustments are necessary.

INSTALLATION: The Model 126 is complete in every detail for efficient
and immediate operation. A self~contained Loop Antenna is included, which
will give excellent results in most locations. Due to the directional properties
of the Loop, it may be advantageous to turn the receiver to the left or right
in noisy locations for maximum signal and minimum noise. A best position
for reception can always be found. In unfavorable locations where distant
reception is required, a well-constructed outside antenna may be used, and
connected to the green wire labeled "Ant." at the rear oi the Loop. A water or
gas pipe may be used as a ground and connected to the black wire labeled
"Gnd." at the rear oi the Loop.

CAUTION: If this receiver is operated on D. C. (Direct Current), and you cannot
obtain reception although the tubes are lighted, reverse the line cord plug to
obtain the correct polarity. Objectionable hum or noise may also be elimi-
nated on A. C. operation by reversing the line cord plug.
