    Another reason I could imagine for the centre tap is so that those who don't know any better (such as me) don't fit the transformer the way around. Does that make sense?

    Which is good for me too - you won't believe how many things can go wrong when those of us with ten thumbs get going!

    Actually this next quote is far more likely...

    This is a bit off topic but do you live in a Library?:D

    Ha, ha. That's just a corner of one room. Luckily we live at an altitude of 6000 feet or all the books in this house would have sunk us long ago!

    Regarding the centre tapped transformer, that guess of mine was actually wrong. I checked through the rest of the book, and no other circuit uses the centre tap. So maybe it really is meant as an aid to help us beginners from going wrong. And Microsoft thinks they discovered user-friendly.

    On the other hand the center tapped xfmr might have been what he had in his junk box.

    The 100k base bias resistor is far too high.
    The transformer is only about 20 ohms
    The designer of the circuit does not understand electronics.

    Collin this is a milestone. You wrote a complete paragraph and it didn't contain a link to your website. Are you feeling OK? :p
