This 1968 circuit is intended to switch the polarization of a satellite TV antenna of the time. The circuit is powered by 12 V and the transistors are from that time.
The output transistor used in this amplifier must have Vce of at least 200 V and Ic of 1 A and...
Found in a 1968 US documentation, this circuit shows how to use the resistance-scale multimeter to...
This filter is inserted between the interfering device and the interfering device. The coils are...
