    Hi All!
    After installing the new version, I needed a high voltage ZETEX transistor ZTX658. Grabbed the model from their site, pasted it to the ltspice standard.bjt file, renamed a standard npn to ZTX658.
    I was a little surprised that this did not work at all.
    Pasting the model into the drawing as a spice directive: Same negative result.
    I am not a regular user: What did I miss? I browsed several tutorials: Can't find a mistake. Can anybody help me?

    Where was this file located? The Windows version of LTS installs it in two places but apparently uses only the file in the \Documents\LTS\lib\cmp folder.

    Thank you for the hint, it helped a lot! I am working on an apple, the standard.bjt the progam folder is not used at all apparently. There is a copy in a place that can not easily be found by guys like me more suited to a windows system. It is located in ./Library/Application Support/LTspice/lib/cmp. Thanks again!
