... there is just one of them … 3 V. Then we look at the deadly “IR Drops” and see to our horror that there are three of them, but at least the current I is the same in each (why ?). So we have to add up 3 x I for the 3-ohm, 4 x I for the 4-ohm and 5 x I for the 5-ohm, giving (3 + 4 + 5) x I or 12 I. Mr ...

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.
