    A different sort of SET amp
    Leave it to Nelson Pass to innovate with the use of SITs.

    Single stage single ended triode behavior class A zero feedback solid state amp!

    SIT = "Static Induction Transistors".Somewhat trode-like, apparently, though I don't pretent to understand how or why.

    Nelson Pass is (in)famous for his brilliantly crazy designs using weird topologies that are, at the same time, consistent his is zero-feedback doctrine.

    NP on the difference.

    His philosophy of using the simplest approach to a problem echoes that of Al Einstein: “When the solution is simple, God is answering.”

    Here are a few fun facts about the Pass SIT:

    *They are made of silicon carbide which allows them to run up to 800 degrees C.
    *Their primary usage is found in governmental radar applications
    *They have extremely wide bandwidth

    I was amused by NP's reference to their cost: click here.

    As for Einstein, it is well know that his references to God were humorous/disingenuous because he was an Atheist. Also, Einstein was wrong about a few things, e.g. his skepticism regarding Quantum Theory about which he commented, "God doesn't roll dice".

    Nelson Pass is another phenomenon. If I had a little more skill and money, I'd attempt one or two of his DIY 'First Watt' designs. By the sound of it I'd need a lot more money to try SIT though.
