  • Notes

  • The Andrea models 1A7 and 3A7 (or 2A7) employ the export chassis type A7L with two Short Wave (13 - 35 m and 35 - 82 m), Broadcast (200 - 570 m) and Long Wave (850 - 2000 m) bands. It has an RF pre-amplifier stage and three IF stages.

    This model was exported to Switzerland (it's listed in the Thali schematic service collection) and France (import by Arce & Co, Paris) and possibly to other Europan countries as well.

    Note: Rider's combines models 1A7 and 3A7 on the same chassis schematics, while the Arce Co. FADA folder mentions 1A7 and 2A7 having the same chassis.
