    Its an easy circuit, 10V voltage source, a resistor and a capasitator in series.
    I got the diagram for how it is charging up, but how do i discharge it in ltspice?

    A voltage controlled switch in series with the supply and a resistor in parallel with the capacitor. In actual practice the parallel resistor is called a 'bleeder' resistor because it bleeds the charge off of the capacitor when the powers is turned off.

    In my linear amplifier the fan is used for this purpose on the high voltage supply. It turns on when the power switch turns the amplifier off and continues to run until the high voltage supply drops to a safe level.

    Really!!! I had none what so ever problems understanding what to OP needed help with. And the same goes for the other persons trying to help. So your posting is in the best case infantile. Unless a typo make you unsure of what the OP want. From this point just ignore them (DoH!)
