WIRING DIAGRAM - MODELS 33 AND 49.

The wiring diagram illustrates a. 5 mld fixed condenser. This should be the value quoted in the table above in connection with the plate bypass condenser. In other words, the 5 med specification in the wiring diagram should be. 3 mfd. The r-f control rheostat shown in the wiring diagram is rated at 20 ohms. The correct figure is in ohms, as stated in the table above.

The difference between the Model 33 and the Model 49 is that the latter has a gold finished panel. The antenna adjustment specification in the wiring diagram is a separately variable plate which is a part of the first tuning condenser. This plate is controlled by a small knob.

The wiring diagram on page 137 of Rider's Manual, Volume 1 shows a. 006 mfd phone condenser. The correct value is as stated in the table above. At the time the diagrams were first published, the values designated were assumed to be correct as secured from supposedly reliable sources. The diagram further shows a 3. meg grid leak. This data was a part'of the original diagram as furnished by the A - K organization. Subsequent to the publication of the original diagram, the parts list for that receiver showed a 2. meg grid leak as advised in the table.

Model 49

The Model 49 receiver is the same as the Model 33 and the parts list supplied above is applicable in its entirety.
