    good day,

    First time posting. My coworker has an electronic hobby and has hit a wall trying to find the following:

    AC180/181 KVII (Gain 7) Germanium transistors

    His exact ask:

    Im looking for AC180/181 KVII (Gain 7) Germanium transistors. I can take Gain of 6 too.... I only need one of each but will take what's available then I can match them if possible. I want to test the gain to get the most symmetrical match I can as this is for a class AB amplifier section.


    Please email me directly at VA6JMD@gmail.com if you can help.

    Hi Justin - I am not sure you will find anything in Calgary and area, but I found a source, that appears to be in Europe, I think?
