  • Notes
  • The Sony models ICR-90 and ICR-120 with 3 transistors, 1 IC (BX201) and two diodes IT26 as detectors are identical - except for the model name. The weight is 0.08 kg. They were released at the same time. The Earphone for it is model ME-25. The ICR-90 is the domestic model for the Japanese market, while the ICR-120 is the export model. There is one small difference in the packaging/accessories, though: being the domestic market model, the ICR-90 was shipped with the BC-90 Battery Charger, which is rated at AC 100 V 50/60 Hz input. As the export model, the ICR-120 shipped with one of two variations of the BC-120 Battery Charger. Those are the BC120W (service part number: Y-3826-01-1), which is rated at 117V AC 60Hz input, (primarily for the North American market), and the BC-120E (service part number: Y-3826-11-1), which is rated at 220V AC 50/60 Hz input.

    The ICR-100 was the first Sony radio with an integrated circuit and that predated the ICR-90/120 by about three years. November 1969 is given in a number of original Sony documents and in an internal "dictionary" for Sony employees.
