Found in an Electronic Design from the 90's, this circuit simulates a 100 W resistor. The power transistor must match the desired current in the load under test.
This power supply with transistor regulation was obtained in a 1995 documentation. The power...
This two-station intercom was found in documentation from 1966. R4 should be experimentally...
We found this circuit in a publication from 1966. The components are from the period. Complete...
