Looks like this lot of transistors is gonna be a high dollar item on
Ebay. Only ten yours left, tho, so get your bids in real soon. ;-)
Yeah, right....

What is the special reason in this transistor?

Not in the transistors, just in the morons with far more money than
sense!

Someone really wants to repair their Western Electric Old Vintage Transistors
radio.

Well, these are point contact transistors, old outdated technology.
That makes them rare, and thus worth a lot to collectors. Or worth a
lot to someone anyway, maybe just someone who wants to resell them for a
profit.

As far as I know, these have never been used for consumer electronics,
and their performance would very likely be too poor for RFs.

At one time, I thought about purchasing some old point contact transistors
to play with -- but the benefit would have been nil. There is some
temptation, but (to me), there is more challenge in playing with
more forward looking endeavors.

However, there is still some temptation to play with some point
contacts (before my time), or get some 2n525s (AFAIR, one of the better
components when my hobby started) to remember the 'good old days.'

Then, reality grabs me again, and instead, I go back to work on
my automatic RF wideband impedance matching program (interfaces
directly or indirectly with spice like programs) for my electronics
hobby, or build another UHF TV preamp concept...

I guess for 'hobby' applications, it really doesn't make much difference
if we are playing with near-state-of-the art, antique or ancient
electronics technology -- the goal is to enjoy the hobby itself!!! :).

These are point contact rather than junction transistors. Transistor
collectors value them because they are rare. The 2N110 is a point
contact unit that was made into the 70's because of it's common use in
industrial and millitary equipment.

Older point contact units like in this auction

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3800110452

are quite a bit rarer and chances are there are not many around. If
you think how important the semiconductor is to modern society, I
think it is a very overlooked collectible as far as collectibles go.
Take a look at what an old edison light bulb will go for now to get an
idea. You have also got to remember that most of the transistors in
the auction above were hand assembled in the lab under a microscope.
They were also VERY expensive in their time. Transistors like the
CK722 and to a lesser extent the 2N107 have a lot of nostalgic value
as the first transistor someone ever experimented with or what started
many a career as an enginneer in later life. Bottom line..people
collect everything.

Take a look at the excellent website here for more transistor history
and lots of pictures.

Yeah, I remember. GE made those, and promoted them for such things as
audio preamps. Then Motorola came out with the 2N1192 series, and
National or Fairchild with the jellybean TO-106 packages such as 2N5233,
etc. And GE had the 2N3391A series, etc. Ah, the 1960s.. Problem was
that I was a starving student w/o money to buy any of that stuff. Now I
can afford it, but I don't have the time or eyesight to do as much as
when I was young. Damn, always something creating a stumbling block..

Then, reality grabs me again, and instead, I go back to work on
my automatic RF wideband impedance matching program (interfaces

And they say that the smell of hot solder has toxic lead in it. I guess
I'll end up buried in a toxic waste dump. They'll analyze my hair and
GASP! and ship me off the the high level nuclear waste facility!

I acquired 5 more CK722s last year, along with the four or five I
already had. Looks like I'll be able to retire on the proceeds. ;-)

Hmmm nice,
