High Voltage Direct Current Transmission - ac

... In 1961 the cross channel link between England and France was put into operation. The a.c. systems were connected by two single conductor submarine cables (64km) at ± 100kV with two bridges each rated at 80 MW. The mid-point of the converters was grounded at one terminal only so as not to permit gro ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
