... and B of the circuit shown. This is correct as far as it goes. The resistor R12 is indeed in parallel with R6. However, we will save some time if we recognize that R7 is also in parallel with each of these two other resistors. We can combine all three of them in the same step, and save some time. Re ...

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.
