Service Data

(1) Line-Up Capacitor Adjustments:
To properly align this receiver, it is essential that a modulated R.F. oscillator, such as Stock No. 9050, an output indicator and an alignment tool (Stock No. 4160) be available. Figure 5 shows the location of the various line-up capacitors.

I.F. Tuning Adjustments:
Two transformers comprising four tuned circuits are used in the intermediate amplifier. These are tuned to 460 K.C. and the adjustment screws are accessible as shown in Figure 6. Proceed as follows:
(a) Short-circuit the antenna and ground terminals and tune the receiver so that no signal is heard. Set the volume control at maximum and connect a ground to the ground terminal.
(b) Connect the test oscillator output between the first detector control grid and chassis ground. Connect the output meter across the voice coil of the loudspeaker and adjust the oscillator output so that, with the receiver volume control at maximum, a slight deflection is obtained in the output meter.
(c) Adjust the secondary and primary of the first and then the second I.F. transformers until a maximum deflection is obtained. Keep the oscillator output at a low value so that only a slight deflection is obtained on the output meter at all times. Go over these adjustments a second time, as there is a slight interlocking of adjustments. This completes the I.F. adjustments.

R.F. and Oscillator Adjustments:
The R.F. line-up capacitors are located at the bottom of the coil assemblies instead of their usual position ont he gang capacitor. They are all accessible from the bottom of the chassis except the 600 K.C. series capacitor, which is accessible from the top of the chassis. Proceed as follows:
(a) Connect the output of the oscillator to the antenna and ground terminals of the receiver. Check the position of the indicator pointer when the tuning capacitor plates are fully meshed. It should be coincident with the radial line adjacent to the dial reading of 540. Then set the Test Oscillator at 1720 K.C., the dial indicator at 1720 and the oscillator output so that a slight deflection will be obtained in the output meter when the volume control is at its maximum position.
(b) With the Range Switch at the "in" position, adjust the two trimmers under the two R.F. coils, designated as BC in Figure 6, until a maximum deflection is obtained in the output meter. Then shift the Test Oscillator frequency to 600 K.C. The trimmer capacitor, accessible from the top of the chassis, should now be adjusted for maximum output while rocking the main tuning capacitor back and forth through the signal. Then repeat the 1720 K.C. adjustment.
(c) Now place the Range Switch at the "out" position, shift the Test Oscillator to 18,000 K.C. and set the dial at 18M. Adjust the two trimmer capacitors designated as SW in Figure 5 for maximum output, beginning with the oscillator trimmer. It will be noted that the oscillator and first detector trimmers will have two positions at which the signal will give maximum output. The position which uses the lower trimmer capacitance, obtained by turning the screw counter-clock-wise, is the proper adjustment for the oscillator, while the position that uses a higher capacitance is correct for the detector. The detector trimmer must be adjusted for maximum output while rocking the main tuning capacitor back and forth through the signal. Both of these adjustments must be made as indicated irrespective of output.
The important points to remember are the need for using the minimum oscillator output to obtain a deflection in the output meter with the volume control at its maximum position and the manner of obtaining the proper high frequency oscillator and detector adjustments.

(2) Radiotron Socket Voltages:
The following voltages are those at the various tube sockets while the receiver is in operating condition. No allowance has been made for currents drawn by the meter, and if lower resistance meters are used, such allowances must be made.

(3) Power Transformer Connections:
Models supplied for 220-volt power supply, use a power transformer having a tapped primary. The tapped primary permits it to be used either on lines of 100-130 volts or 195-250 volts. Figure 5 shows the internal connections of the transformer and the voltages to be used with the various taps. The taps are located on a terminal strip at the top of the transformer so that necessary changes may be made without removing the receiver from the cabinet.

Insist on genuine factory tested parts, which are readily identified and may be purchased from authorized dealers.
