... Sometimes you need a kind of resistor, but you don't have it on hand and it doesn't exist. Fortunately, it's possible to use several different resistors in combination to get virtually any level of resistance, for example if you have 2 resistor of 20 Ohm and you need a resistor of 40 Ohm, just add b ...

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.
