Notes This first pocket transistor radio from Raytheon Mfg. Co., the radio model T-100, came in 5 different colors: T-100-1 = black/yellow, T-100-2 in ivory/yellow, T-100-3 in black/red, T-100-4 in ivory/red and T-100-5 in ivory/gray. Raytheon made it under the license of RCA and customized it also for Hallicrafters as model 4RT3, Airline as model BR-1102A and for Truetone as model D3715A in Turquoise. There are different schematic sources depending on the brand. Some have different values. Please check here for more information about this model family and about the differences.

Right front round brass dial with below a thumb wheel on/off/volume knob or wheel in front. In the middle a checkered grill area. The right is a free area for brand, name etc. 1 Germanium diode. No reflex circuit used. Earphone receptacle. For the semiconductors see the equivalent list by clicking the one you need on the list of the four transistors.

Interesting: For Hallicrafters the case was reversed and the thumb wheel on the front was turned into a thumb wheel on the top. Clever idea to hide its origin. See about schematics and differences between them in this explaining text.
