Following Hoffman’s successful production and marketing of their 6-transistor Model 706 Trans-Solar radios they announced on July 11th, 1961 this smaller AM band 9-transistor Model 709 transistor radio. Initial retail list price was $49.95 and it was available in four cabinet colors (TP-709 – Turquoise), (KP-709 – Black), (BP-709 – Brown / Tan), and (OP-709 – White). Some model numbers were assigned an “X” or “XS” suffix (i.e. OP-709XS).
As can be seen in the examples pictured here, several different diffusers covered the solar panel. In addition, the actual solar panel units themselves varied somewhat in assembly and of the individual cells used (note the tan example with the same panel used on the earlier 706 Trans-Solar models!)
