Description

The AT-1 9/80-Z is a mains power unit for transistor radio receivers, made by Electronica in Bucharest [1]. The Dunărea S 662 TA table radio ran from the mains through a built-in AT1 unit [2].

Electronica made several mains power units for its transistor radios, each matched to the sets it was used with: AT-1 (9 V, 80 mA), AT-2 (9 V, 300 mA), AT-3 (6 V, 200 mA) and AT-4 (9 V, 300 mA) [1].
