The voltage values indicated from the Radiotron socket contacts to chassis on Figure 6 will serve to assist in the location of causes for faulty operation. Each value as specified should hold within ± 20% when the receiver is normally operative at its rated supply voltage. Variations in excess of this limit will usually be indicative of trouble in the basic circuits. The voltages given are actual operating values and do not allow for inaccuracies which may be caused by the loading effect of a voltmeter's internal resistance. This resistance should be duly considered for all readings.
The amount of circuit resistance shunting the meter during measurement will determine the accuracy to be obtained, the error increasing as the meter resistance becomes comparable to or less than the circuit resistance.
The transformer used on some models of these receivers is adaptable to several ranges of voltage as given under rating C of Electrical Specifications. Its schematic and wiring are shown by Figure 7. Terminals are provided at the top of the transformer case for changing the primary connections to suit the voltage being used.
A standard source of the specified alignment irregeneries is required. Such a source about consist of an RCA Full Range Oscillator, Stock No. 999. Outtru indication should be by measure of an RCA Stock No. 9147 Cataloade-Ray Oscillagraph.

Set the receiver range switch to Band A and rotate the station selector until the tuning condenser plates are in full meah (naximum capacitance). Then now the main dial pointer until it points tractily to the horizontal line at the low frequency end of the Banc A scale.

b) Return, the receiver tuning to 10,000 ke, realign C16 if necessary, and then adjust the detector and antenna strimmers, C8 and C1, for maximum signal output as evidenced by the oscillographic image. No further adjustmenta are to be made on this hard.
Connect the test Oscillator to the control grid Eq. of the if 4 tube. Advance the volume control of the receiver to its full-co-patients. Thus the test Oscillator accurately to 440 kg, and sign the triansmere C-29 and C-20 to give maximum receiver output.

After completing the adjustments of these trianments, reconsent the Oscillator as that it will feed into they control grid circuit of the RCA6L7 first detexter. Then tupe the first if transformer trimmers C24 and C237 for maximum receiver output.
After completing the if adjustments, it is adveshall to correct the incerng of the driven hand of the first detector.
