Daniel,
Good for you!
It is my impression from watching scarce items like this that there are many companies that will advertise an item at an outrageous price even if they don't have it. They rely on finding some other company that claims to have it and then if you meet the price that justifies them actually hunting down a real copy the will do that and pocket the difference.
The reality is that all there needs to be is one copy and these companies make it appear that there may be more than one copy or even many. Daniel discovered that in the case of Stan's book there was only one copy. Now the price has jumped back into the stratosphere where it usually is.
I suspect there isn't more than one (or two at the most) of the Typical Oscilloscope Circuitry books either and now that Daniel bought one of them I think the price will skyrocket like Stan's book did.

Hi Folks,
The recent conversation about 500 series scopes prompted Dennis to
recommend two books,
"Oscilloscopes: Collecting and Restoring a Classic"; ISBN-13:
9780963307156; Publisher: Stanley A. Griffiths; Publication date:
01/28/1992;
"Typical Oscilloscope Circuitry", (C) 1961, 1962, Tektronix,
Inc., S. W. Millikan Way, P.O. Box 500, Beaverton, Oregon.
It occurred to me that though I have not *needed* those books to
repair my scopes in the past it sure would be nice to have a better
Idea on how the circuits work, and to be able to learn more about the
scopes in general, so I looked them up.
YESTERDAY, I was able to find a couple copies of Stan's book on
Amazon, used, for about $22. If I still have the website up at home
and it has not refreshed, I'll get a screen grab for proof, but there
were one or two copies available from at least two sources, through
Amazon. But TODAY, the least expensive copy is $94.09!! So, it
seems likely to me that this very discussion, within out closed group,
prompted someone to buy a book or two, and those actions drove up the
perceived demand on a limited resource to raise the price
significantly.
Question: Did anyone here, reading those messages yesterday go
ahead and buy Stan's book on line? What was your price and through
whom did you make the purchase? I sure HOPE that someone here bought
the book. Otherwise, I have a more nefarious theory; The bots are
actively scanning our conversations to manipulate the prices of things
on line. That is not a pleasant concept.
I found a copy through Moe's books for $28 and bought it. Let's
see how the price changes tomorrow.
As for the Tek book, "Typical Oscilloscope Circuitry", also found 3
copies in good condition for under $20 and bought one. We'll see
what happens to that as well.
I just figured I'd throw this out there as an FYI / buyer beware
sort of thing. Meanwhile, I am looking forward to some fun technical
reading!
Dan
