    I want to make a pre amplifier circuit for my 10kV power supply.
    can anyone suggest me the amplifier with high voltage gain. I've worked on LM-741 but its gain decreases when frequency increases.
    :(

    What exactly would a preamplifier for a 10kV power supply do?

    as input is just a simple 9v portable battery so in order to amplify the signal i'll use pre-amplifier stage.

    So where does the ten thousand volt (10kV) power supply come in? Or was that a typo?

    What "signal" do you want to amplify? You know that you can't "amplify" a 9V battery to produce 10,000 volts, don't you?
