With its "genuine superheterodyne circuit ... The Regency was the first transistor product for the mainstream. A relatively simple 12-ounce AM radio, it marked the turning point from analog ...

One of the first electronic projects I worked on was just such a circuit ... Transistor Radio. This book built the reader up through a series of steps to a fully-functional 3-transistor Medium ...

This two transistor AM radio circuit is also called “mini-radio”. It uses only 2 transistors and few passive components which makes is very easy to be constructed. Although the circuit is very simple, ...

that work well for radio reception. The 120k resistor is for regenerative feedback between the Q2 NPN transistor and the input to the tank circuit. The value of this resistor is important to the ...

The humble transistor radio is one of those consumer devices that stubbornly refuses to go away, but it’s fair to say that it’s not the mover and shaker in the world of electronics it might on ...
