    Convert 0-30V 3A PSU to 5A or more

    mastrila, Have you measured the voltage at Q4 collector when doing these tests? Is here enough voltage to supply the output or are the transformer and rectifier dropping too much? If there is plenty of slack here the problem is in the controlling part. Measure the base to emitter voltage under...

    741, TL071, LF351, NE531, TL061, TL081 IC tester

    Why waste components for a tester of something you test once or twice. The cost of this tester will exceed the price of some new op-amps. I think for an amateur the money is better spent on a protoboard on which you can make a temporary test bench for any IC and of curse use for a lot of other...

    Car stereo amplifier output ratings

    The Mosfets works more like a vacuum tube than the bipolars, maybe they want the tube sound. The vacuum tubes are also sensitive devices..... if you drop them! ;D Ante ::)

    Light Switch

    Audioguru, The power surge is one of the reasons I want to use a Schmitt trigger if the light comes on slowly the transistor will be fried before the lamp starts to glow. If the transistor is driven directly to saturation it can cope much better with the current. Ante ::)
