I'm gonna have to side with Eric on this one. =C2-I think you guys are in
a nostalgia induced somnambulism that results in tons of worthless cr*p la
ying around the house. By worthless, I mean things that you will never use
again. You'll just walk by it and admire it occasionally as you worm your w
ay through the make shift aisles to the kitchen for yet another Ruben sandw
ich. Some people call it hoarding.
The Tripplet 630 was a fine instrument in its day, but it was made for rela
tively high voltages and empty state logic, not the low voltages and curren
ts in today's solid state devices. Yes, you can use it to trace wires and f
ind some resistance problems, but as a general all around instrument, you m
ight as well take it with you when you die and donate it to Nicolas Tesla w
hen he greets you at the Purrly Gates. I'd much rather have my trusty Fluke
77 or 87 to troubleshoot just about anything, including my mistress going
haywire when she finds out I'm married. I have both instruments, one for th
e hangar and one for the house. I'm even thinking about getting another one
for my bar hopping trips so I can check out women's resistances as I appro
ach them with my teleprompter and well rehearsed lines. Yes, it's that vers
atile!
As Eric Jonez said, the 77 is a darn good instrument. =C2-I've had mine f
or over two decades now, and it is indeed a trusty instrument with a nice y
ellow protective cover. When I die, I'm gonna take it with me so I can have
William Shockley meet me at the Purrly Gates and tell me I made a fine cho

Good Morning Jeff,
Just waxing nostalgic I guess.
I have a Simpson 260 in one of those beautiful sliding cover cases that I
just cannot let go. I also have several Fluke 77s around. However, the 26

What's this about taking sides? If
anything, this thread has been a cognizant
observation of what these tools represent
in utility, history, and teaching value.
I don't think anyone has suggested that the
260/630 genre' of tools is a substitute for
modern digital instruments. At the same time,
there are things an analog instrument will do
for the observer that a digital instrument cannot.
I still have a lot of vacuum tube era parts
and tools. It is my plan to use them as teaching
tools for my grandchildren . . . assuming they're
interested. Building a vacuum tube receiver or
transmitter requires some skill development in
schematic reading, stripping wire, soldering,
chassis layout, punching/drilling holes, winding
coils (after we calculate how big they should
be), measuring voltages and currents (yes, the
630 will do nicely).
Something a vacuum tube offers that a transistor
can never offer is that you can take it apart.
Hold, feel and see the pieces. Imagine the
boiling of electrons off a hot cathode for
launching toward plate. This, like the experiments
of Hertz, Helmholtz, Faraday, Volta, Ampere, et. als.
is hands-on, see-it, feel-it physics.
At the other end of the spectrum, programming a
micro-controller is a purely intellectual exercise
that has nothing to do with electronics . . . but
without it, you cannot exploit the value that
electronics can deliver. They are joined at the
hip. The elegant solutions are achieve a working
understanding of both.
When I was in high school, the school board
was participating in a dual-track science education
experiment. One group of students took chemistry
and physics in the contemporary setting while
another group studied using more 'modern aids'
like films and 'less sophisticated' and hardware-
store/lumber-yard tools and materials. This was
carried out in two Wichita high schools. The
question to be answered was, "Can science be
adequately taught in less endowed schools using
more rudimentary tools and processes?"
Don't know how powers-that-be viewed the
outcome of the studies for teaching methods.
I took the experimental course in chemistry.
I found out from my chemistry teacher years
later that I made the highest score in Wichita
going in, and the highest score coming out.
I can personally attest to the fact that the
shiny tools and latest processes do not drive
the outcome of a teaching process so strongly
as modern 'educators' would have us believe.
I think the point of this discussion is to
explore the physics and utility of any tool
for understanding and without prejudice for
it's less than modern shortcomings. Would
you similarly denounce a builder's choice to
build a replica J-3 as opposed to a Sonex?
If this discussion was about applying modern
materials and systems to a 1940's restoration,
would you decry the effort as whipping a
dead horse? As one of my heros, Richard Feynman
suggested in the tile of his book, there is
a lot of pleasure to be gained from finding
things out.
http://www.youtube.com/watch?v=Bgaw9qe7DEE&feature=related
Those who do not find pleasure in such endeavors
are certainly free to focus their efforts elsewhere
but let us refrain from obstructing the pleasure
of others.

While the modern digital instruments can be inexpensive and exceedingly
accurate, sometimes that accuracy can be an issue especially when
dealing
with changing values. Trying to visualize constantly changing numbers or
even read their value if the changes are rapid can be very frustrating,
sometimes impossible. The old analogue instruments, while they may not
read
to the ultimate resolution, average changing values very well and in
that
dynamic situation, where the digital is useless, can give a nice,
relatively
stable, easy to see, reading. If what you=92re looking for is a steadily
falling or rising value, then the analogue will show a nice steady
needle
movement (or an erratic one to show a not-so-steady change) whereas the
rapidly changing numbers on a digital display don=92t help. You=92ll
have almost
no idea of what is going on. (Measuring the resistance of a
potentiometer
with both a digital and an analogue meter while smoothly turning the
shaft
from one extreme to the other to determine if there are any dead spots
or if
the pot is a linear or logarithmic taper for instance will quickly show
the
superiority of the analogue meter. If you want to know the precise value
of
a fixed resistor then the digital will be superior)
In short both types are useful. Sometimes the digital is better,
sometimes
the analogue beats it by a mile. As in most things - - =93It depends=94
Only my .02=A2 opinion

Hi Group
I rescued a Triplett 310-C from certain death about two weeks ago.
It's missing the leads for them, anything I have doesn't fit.
Any ideas about getting how to get hold of a set?
This unit takes two 1.5 volt batteries, not sure what size.

Well, by your definition: "just walk by it and admire it occasionally"
makes it cr*p. All art is cr*p. Gotta disagree.
I'll say no more on this topic because it doesn't further electron
herding skills.
Thanks to everyone for sharing their opinions.

Understand. My do-do list is immeasurable and constantly
getting stirred by a 'pleasurable curiosity' of the moment
. . . I readily confess to being ADD on a grand scale.
It probably frustrated my teachers but since I wasn't disruptive,
they left me alone to suffer my intellectual chaos in
private. So back to the sheet rock and plumbing task at
hand . . .

Bob,
There was a Simpson 260 in my dad's stuff as well - in the same kind of case
as you describe. I think it will get a place of honor on the test bench,
too.
Just for grins I looked on ebay: they go for $20-$200. Does anyone remember
what they sold for new?

I've not run across that model before. Here's a link to
the list manuals for Tripplet legacy products:

The battery call-outs are:

Wow! The 1.5 volt cell is an "N" which are still
very much available . . .
http://tinyurl.com/9ozgmtj
The 15v is too . . .
http://tinyurl.com/8okd49r
But a bit more expensive. Again, replacing the
n-cell only might yield a very serviceable
device.
I think those test lead jacks accept the miniature
banana plugs.
Here's a link to a surplus store in Orlando
that has some $high$ Pomona patch cords for cheap with
what I believe is the right sized plug. A couple
of these modified on one end with alligator
clips would get you some leads. You could cover
one of the clips with a red boot and suitably
mark the other end to encourage insertion to the
(+) jack.
When you get it running, show a kid what it does
for you.

Yup, at least in 1961 both the Tripplet 630 and Simpson 260 sold for
about $70. That's about $500 in today's dollars. It was a week's
wages for me at my first job in aviation at Boeing.
