Notes

The General Electric P-797A is a portable battery operated 5 transistor AM band receiver.  The AM band frequency tuning range is 540 to 1600kHz.  Has built-in loopstick antenna.  Uses Qty(4) "D" 1.5V batteries.

This model is part of the P-795, P-796, P-797 and P-798 family of models, which have the same cabinet but have different colors.  The various letters behind each model number indicate the circuit differences.

Model Family "A" Version "B" Version "C" Version "D" Version "E" Version Cabinet Color
P-795 P-795A P-795B P-795C P-795D P-795E Black
P-796 P-796A P-796B P-796C P-796D * Blue
P-797 P-797A P-797B P-797C P-797D * Beige
P-798 * * P-798C P-798D * Maroon

* - Indicates model does not exist

Different types of transistors possible - see slightly different parts on the notes of the schematic. Batteries for normal usage of 175 to 250 hours. Leather case, right side tuning knob, left side on/off and volume knob.

The SAMS Photofact Set 421, Folder 8 calls out models P760A and P761A. However the SAMS index for model P-797A refers to this same Set and Folder and so therefore is applicable for this model also.
