High Voltage Solid-State Circuits for Tube Guitar
... voltage rating of 500v, it should work well in preamp stages of most tube amps. The 100 ohm resistor is there to suppress H.F. oscillations. If IRF820 is physically close to the 12AX7 plate, you probably won't need it. You can see how the MOSFET is equivalent to a triode: Source = Cathode; Gate = Gr ...

... The AD8603 is configured as a subtractor so that it can reject the 5 V common-mode voltage and amplify the signal of interest, IS × RS. The signal is amplified by a factor of 20 to span the 2.5 V full-scale input range of the AD7453 ADC. A fullscale 2.5 V signal to the ADC corresponds to a current ...

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.
