This is a typical circuit for an old microwave oven. We took it from an August 1973 Radio Electronics magazine, from an article that taught how to make repairs.
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...
