This power supply uses a single-winding transformer. We found it in July 1984 Radio Electronics magazine. The integrated circuit must be equipped with a heat sink.
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...
