MODEL 125Z

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.

TUNING RANGE: Broadcast: 540 to 1650 Kilocycles (180 to 555 meters).

DIAL: The Dial Scale is calibrated in Kilocycles times 10 to co
correspond with newspaper or periodical listings.

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

12BE6 Converter
12BA6 I.F. Amplifier
12AT6 Detector, Avc and Audio Amp.
50B5 Beam Power Amplifier
35W4 Rectifier

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 eliminated on A.C. operation by reversing the line cord plug.

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

(1) Set the Signal Generator to 455 KC and connect to the Stator Lug on the rear section of the Variable Capacitor. Connect the Signal Generator ground lead to the chassis. Connect a suitable output meter across the Speaker Voice Coil Connections. 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. Transformers for maximum output as indicated on the output meter.

(3) Loosely couple the Signal Generator Ground 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.

TRIMMER AND TUBE LOCATION DIAGRAM

INSTALLATION: The Model 125 - Z 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 of the Loop. A water or gas pipe may be used as a ground and connected to the Black wire labeled " Gnd. " at the rear of the Loop.

MINOR REASONS FOR FAILURE TO FUNCTION: Defective tubes, defective Volume Control and On - Off Switch, line cord reversed on D.C., defective line cord plug.
