Scribe Notes
... We want a way to connect a voltmeter without loading the system and lowering the voltage readout (remember that a resistor in parallel lowers the voltage read between two points). What is loading the system? Loading the system means to draw current from it. Real voltmeters and ammeters will do this ...

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.
