Remler 49,171
The Remler Model 171 is identical with Model 49, shown on page 2-3 of Rider's Volume IX. The following additional information, not included on page 9-3, is now available.
The antenna - RF coil is located near the back of the chassis and is trimmed by the trimmer on the rear section of variable condenser. The detector coil is located under the chassis and is trimmed by the trimmer on the front section of the variable condenser.
The following table shows the d-c voltages to ground with no signal and the volume control at full volume.

The d-c voltage of the bias supply for the 41 grid is a 15 - volt drop across resistor (9) in the negative side of the power supply.

Airline 62-362 issue B

Several changes are included in Is sue B of the Model'62-362 Airline receiver (above serial number 8J285 200) as compared with the Model 62-362 shown on Montgomery - Ward pages 9-45 to 9-47 of Rider's Volume IX. Fig. 1 shows that condensers C1, C4, C5, C6, and C9 are mounted in the same unit in Model 62-362, Issue B. Fig. 1 of course corresponds to the layout shown in the upper left-hand corner of page 9-45.
Fig. 2 shows the output end of the schematic for Issue B of Model 62-362. By comparing Fig. 2 with the corresponding portion of the schematic shown on page 9-45, you will notice the new position of the tone control consisting of R14 and C20, and also the two resistors R16 and R17 added across the winding of the phonograph pickup coil.

The accompanying table lists the part numbers and descriptions for Model 62-362 Issue B which are dif ferent from those listed on page 9-45.

Philco 630, 630PF
Certain oscillator trimmers are in correctly numbered on pages 6-32 and 6-33 of Rider's Volume VI (early model 630 Philco). In Fig. 2 and in the alignment instructions, both on page 6-32, the reference numbers should be changed as follows: Change 13 to 16; change 14 to 17; change 16 to 13; change 17 to 14. The same changes should be made in the parts list on page 6-33. These changes must be made so that the reference numbers will agree with those shown on the schematic which appears on page 6-31. Do NOT alter the numbers on the schematic
These errors in numbering also appear in the parts list for the late Model

630 and the Model 630PF Philco. Therefore the reference numbers on page 7-98 of Rider's Volume VII must be changed as follows: Change 13 to 16; change 14 to 17; change 16 to 13: change 17 to 14.

Stromberg 160 - L
Variations in new 6J7 tubes have occasionally caused distortion in the automatic tone-control circuit of the Stromberg Model 160 - L receiver as first released. These tubes function correctly after " aging " a few hours.

By adding the wire indicated, distortion can be eliminated from the automatic tone control circuit of the Stromberg
Model 160 - L

This possibility of distortion can also be eliminated by adding a wire as shown in the accompanying layout. This change stabilizes the screen volt age; it was put in effect at the factory in all 160 - P and 180 - L receivers, and in all 160 - L receivers produced after October 23, 1936.

Philco 37-62
In order to eliminate oscillation, the screen resistor, No. 11, has been changed from 25,000 ohms to 32,000 ohms. See schematic on page 8-19 in Rider's Volume VIII,

Fairbanks - Morse 12A
Refer to the schematic shown on page 8-11 of Rider's Volume VIII. During production, the 47,000 - ohm re sistor in the AVC line which was con nected to the bottom of the antenna coil secondary, and the condenser (4) were removed. The rof secondary was then grounded directly, thus removing AVC from the 6L7G mixer tube, and the bottom of the antenna coil second ary was connected directly to the re sistor (16). The condenser (33) in the grid circuit of the 6C5G oscillator was changed from 50 mmf to 100 mmf to increase sensitivity on the u-h - f band.
