Changes
Model 82-D Replacing IF Bias Resistor No 19830. A new style I.F. Bias Resistor has been developed to supersede the old style resistor. The new style resistor carries the same part no. and is installed exactly like the old style resistor.
Replacing Filament Series Resistor No. 1
Original no. 19850 resistor this is replaced by resistors as shown at right.
Replacing Filament Series Resistor No. 1 in model 82-D
1. Remove original no 19850 resistor.
2. Mount one no. 25980 and one no. 25990 as shown in lower left darwing.
3. Connect these two resistors in series as shown in drawing at right.
Change in model 659 to eliminate radio interference when using phonograph.
New Arrangement
Parts required

Schematics for #21F unit on E-145 set to improve selectivity
Atwater Kent Radio
Changing early model 155 to use 75 tube in place of 85. This will provide greater output.

IF PEAK 262.5 KC.
In late type 165, the 1st-detector bias resistor R2 is 2000 ohms, 1/2 watt
In a few early 165 sets, the tracking condenser C3 is 680MMF.
In late sets, C1 is 25MMF instead of 50MMF.
The additional primary, shown in dotted lines on No. 1 R.F.T., is used in some 165 sets.
