    how can stabilize the mosfet's drain current help (linear amplifier)

    hi, i have this linear amplifier project http://tzitzikas.webs.com/irf640-1.JPG with 2 irf640 mosfets. My problem is, when i adjust the both mosfets drain's current at 400mA (current without input signal), after some minutes when the heatshink is warm (with input signal), the current becomes...
