    What is the simplest, most accessible way to generate a 300-400V
    spike, continuously adjustable within the frequency range of 200Hz to
    2KHz? I am doing exps with powering a 20W industrial gas lamp.

    ** Do the spikes need to be all of one polarity ?

    If bi-polar spikes are OK, then try driving a small mains transformer
    connected in reverse sense to normal ( say 12 volt to 240 volt ) with a
    differentiated square wave that is varied between 100 Hz and 1 kHz.

    You will need an audio amp like the TDA3020, a 555 to generate the square
    waves and coupling cap chosen to get the right spike energy.
