This powerful high-fidelity amplifier was described in an article in Radio Electronics magazine in December 1973. Note the use of 8 high-power transistors that must be mounted on excellent heat sinks.
This medium wave commercial receiver from the 1960s was found in a Japanese publication at the...
We found this circuit in a 1967 Electronic Design. The circuit used a MOSFET of the time, which is...
This step of two transistors has a high input impedance due to the use of FET. We can use BF245 for...
