Notes

The Canadian RCA Victor model A31 has station buttons. The schematic (at Radio College of Canada) shows that the Canadian General Electric model JK-70 (table) and JK-76 (console) share the same schematic, and also share the same schematic as the Canadian RCA Victor A-22 (table). They have a built in loop antenna, called Beam-A-Scope. The wave bands are: Standard Broadcast (A) 540 - 1550 kHz, Short Wave (B) 2300 - 7500 kHz, 31 meter band 94950 - 9700 kHz, 25 m 11,680 - 11,920 kHz, 19 m 15,030 - 15,380 kHz and 16 - 13 m 17,700 - 22,000 kHz. The power Supply Ratings are for "A" 50-60 Hz, for "B" 25 - 60 Hz.
