    can you help me please??
    i have to simulate a circuit for a thyristor controller and in this circuit there is a Zero ADJ it looks like varistor but the input goes into the resistance.it think it verify the zero point of the graph.
    and the other thing is a phase angle ADJ it look like ZERO ADJ but it controll the firing angle of the thyristor.The question is i can´t find the symbol of this ADJ into LTspice lib.what should i do ??is there any symbol?where i find it to make the simulation??

    Ramirez19,
    You've basically "hijacked" a thread that has been inactive for years.

    Unless your topic is the exact same as an existing thread, you should start a new one.

    Expect your post to be moved to it's own thread once a Moderator sees it. Just for reference, the hijacked thread is here: http://forum.allaboutcircuits.com/showthread.php?t=11015

    You need to post an image of the circuit that you are referring to. .PNG format is preferred, as these files are compact, not lossy like .JPG files, and you don't need any special software to view them. .PDF files are also OK.

    Hello,

    SgtWookie is right.
    Better start a new thread when you have a question.
    Now you have your own thread, where you get your own attention.

    Are you referring to the bias of a Diac triggering a Triac?

    Hello,

    Somehow the threads got separated.
    I merged them back together again.

    Perhaps the OP can post a schematic, so we can give better replies on the topic.
