... First, use a small amplitude sine wave for the input voltage and try varying the dc offset voltage of the frequency generator. You will find that a dc offset or an input amplitude that is too large can easily cause the amplifier to saturate, giving a distorted or "clipped" waveform. What + and - out ...

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.
