Set the frequency of the signal applied to the RF IN a few Hz higher than the signal applied to the LO IN, then a few Hz lower, looking at the difference frequency on the output J6. The output level should shift positive or negative depending on whether RF I ...

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.
