c.1960/61 Philco T-51
Shirt pocket radio, thermoplastic cabinet
4 5/8 x 3 1/8 x 1 7/8 inches / 117 x 79 x 48 mm
Five transistors (Philco, T-1001, 2x T-1005A (gold colored), T-1460, T-1542, one diode (1N60A)
Two very small P-640 2.6V batteries
One of my very favorite US shirt pocket radios, plain and simple in design and very much overweight, impossible to mistake for a slim and sleek Japanese shirt pocket radio of the time. This example appears to have been made in 1961 but the T-51 model may have begun production in 1960.
