Notes

Just a few weeks after Regency (IDEA) has launched the first transistor radio, Regency TR-1 with 4 transistors, Raytheon brought its much bigger 8TP with the models 8TP-1 (tan leather), 8TP-2 (brown leather), 8TP-3 (beige leather) and 8TP-4 (red leather) - all in 1955 and with 8 transistors really outperforming TR1. This was the second transistor radio built in series in the world, followed by SONY models (e.g. TR-55). But the first SONY to appear in the USA was TR-63 in 1957. See also the pocket transistor radios from GE as models 675, 676, 677 and 678 depending in color from 1955. The 8TP1 was immediately followed by a 7 transistor with the same model names! 

8 Raytheon transistors (see the two schematics on the model page for 8TP1): 2 of CK761 (oscillator, mixer), 3 of CK760 (IF and detector) and 3 of CK722 for audio (driver, push-pull).
The first series had 5 x CK760 and 3 x CK721.
