This 1960s Japanese receiver uses 6 germanium transistors, being powered by a 6 V voltage obtained from large batteries. The circuit is for the medium wave range of the superheterodyne type.
Found in National Semiconductor publication from the 1980s. This gain-100 circuit can be...
We found this configuration in a 1975 publication. It can be implemented easily, as it uses only...
The high number of transistors on this radio for the medium wave range is an indication of its...
