    can anybody help me
    I wat to amplify a voltage signal of 2 V to 90 V
    How can I do this without using op amps?

    You could just go for a DC-DC converter with linear proportional output.

    We used to use a module from farnell, 5w I think, 12v input 1500vdc output.
    I had a look on thier site but don't think they stock that one anymore.

    google linear HV DC-DC converters

    yeah right
    but the problem is that I want to avaoid the noises produced in that technique
    can u please suggest some transistor circuit that will do me the job?

    You have to be more specific; d/c, a/c, frequency, power in, power out, power supply, efficiency, etc.
    One example could be a CRT video driver. They are usually found on the board on the neck on CRT's, and amplify 1V dc (to 5-25MHz) up to around 90V. They usually require a PSU around 110-130V dc and operate at a power level around 1-2W.
