Model: All American Transistor Convair P-990 - Automatic Radio Mfg. Co.;

Shape
Portable set > 8 inch (also usable without mains)

9 x 6.5 x 3 inch / 229 x 165 x 76 mm

Notes
May be the same schematic as the Canadian P-990.

The Canadian P-990 schematic shows 6 transistors and 2 diodes; it's likely that the American P-990 version uses 2 transistors configured as diodes, leaving 6 transistors that count.
