    In circuit transistor tester

    :)audio guru the leds blink acording to the condition the transistor is in. look at the panel on the on the picture of the in circuit transister tester. it will show you . the white dots are for when the leds blink to indicate , wheather there npn or pnp and which legs are faulty arcording to...

    In circuit transistor tester

    :) thanks hot water wizard and audio guru its a nice pastic box with metal pannel at front with the 2 leds and switch the circuit box has the leads runing out the top end for the base ,emmitter and collector. so with the push down clips its easy to attach to the transister legs . at the top end...

    Transistor tester

    audio guru those clips are push down types that has a coper hook thing that enables me to clip them onto the transister legs, and if i test the 2n3055 npn transistor, because it only has 2 legs and the body is the collector i just push down on the third clip and touch the coper hook to the body...

    Transistor tester

    :)audio guru my in circuit transister tester dosent use intergrated circuits and i think the circuit i use works by shorting out the leds, something like that and the less parts it uses makes it really easy to biuld. mine works great .and gives great indication of any shorts between any legs of...

    pop filtering

    :) i tired this simple experiment agers ago, with a photo flash unit from a pocket camera. first id charge up that 330 volts capacitor in the photo flash unit of the camera, then id dump that charge right smack into the coil of a small speaker, but i was exspecting the speaker to blow but it...
