TDS5xx, 6xx, & 7xx Series scope history
Hello All,
Today I was doing some research about a TDS754D and found that you could go to the TEK website and run a search for the model number and serial number. The info provided will tell you who the scope was originally shipped to and on which date.
I was just goofing off and I think the last TDS754D scope was serial number B041827 sold to Rockwell Collins on Dec 31, 2002. There are no other entries beyond that serial number. So that begs the question...............could that be the last serial number of this scope produced and sold to a customer?
Hope this info helps someone.
Cheers,
David

Oh dear, the albums interface is very very bad... I hope groups.io is working on it... Found the album though: /g/TekScopes/album?id=42121That is an interesting challenge. An extremely condensed gothic that was around the 1950s(?) and 1960s era... Most likely we will only get something "close" and as you already see, there is some variation in the font used for the model numbers (although the TEKTRONIX INC must be consistently used standing artwork). Let me mull over this, the actual faces are probably in long lost photosetting or (in the 50's) metal catalogues, but you'll need something that's easily available in digital today. Luckily there are lots of "similar" modern designs, I'll just have to rummage for them. --Toby I tried with a scanner but of course, the spines are round... and brittle. They'd probably crack if I tried to flatten them.

Well, it does bend AND cut both leads so... ;)

invaluable.

There are also pliers that can be adjusted for width that perform the
same function. I have a pair with pointed tips that you turn a thumb
wheel until they fit in the board holes, and the you stick the part in
press the clamp trigger, and bend the wires with your fingers.

Re: I would like some input on a good wire forming tool.
The largest problem I have found with the plastic
bending guides is they are too large, with the pocket
that the component fits into too small. They worked
very well when component densities were typical of single
or double sided boards, but as densities climbed, they
were useless.
Put another way, they are fine for 1W through 1/4 watt
resistors, but not for 1/8W.
I have had a little better luck with the bending pliers,
with all but the smallest parts.
I used to assemble a lot of through hole assemblies, but
now it is SMD, and my assortment of clipping and bending
tools aren't needed very often.

Chuck,
Thanks. I figgered they were used for bending leads, I was just unsure how one
utilized those tools. I've only used smooth needle nosed pliers of different shapes
to put the bend in the components using the TLAR (That Looks About Right) method of
measurement. Those look like handy little tools to have around.

You put the axial part in the middle of the
guide, with its leads in the lead slots for
the proper hole separation, and then push the
leads down to bend them at 90 degrees to the axis.

I made another tool (back in the day) out of a

the resistor leads into a "U" to space them up
from the circuit board... but that is another
story.

Re: I would like some input on a good wire forming tool.
Select the proper notch, insert part and push the leads down until they are parallel to the tool. That set has multiple widths to make it easier than the old design, where you had to center some parts in the gap.

Re: I would like some input on a good wire forming tool.
I used a pair of needle nose to bend the leads, prior to find the block. I would simply find out how far from the tip would give the proper length, and bend the leads one at a time, but the block was much faster and put less stress at the bend by using a slightly larger radius.

Re: 7633 fan possible to repair?
Hell thanks everyone for all the good info !
I am having a similar issue with the fan motor on my ancient Tek 317. As a previous poster said : "nice, this fan is really quiet ! " ... thought exactly the same about my 317 when I first got it (having no prior experience of any classic Tek), then after an hour of running, suddenly the fan would accelerate significantly, as if it decided to switch second gear so to speak, to what seemed to me like a more plausible speed...
I dismantled the motor, lubricated it with fine machine oil, exercised it by hand for several minutes.. didn't seem to make much difference to me.
So I was about to give up and replaced it with a modern/plastic fan, while hunting for a replacement fan, if such a thing can still be found these days, that is...
So before I give up, I will try to first clean it as much as possible before oiling it, then exercise it a lot more than just 5 minutes by hand.
Should this fail anyway, can this motor still be found, do people sell these things ? If I can't find one coming from a 317 scope, was this motor also used in other classic Tek scopes (or some other kind of instrument, who knows), or maybe not exactly the same, but something close enough, that would be mechanically compatible ? I assume all 300/500 scopes, being of the same era, had similar/close designs and that there must be some degree of interchangeability between models ?? That would definitely increase my chances of finding a suitable motor.
According to the service manual, the part number for the motor in the 317 is 147-001 if that's of any help.

Re: 485 power supply switching transistors Q1834 and Q1844
John
The MJ13015 ( Looks like a? Motorola part #) crosses to NTE2319
DUX48A crosses to a NTE386, the data sheets are very similar.
Both of the NTE parts have data sheets on the NTE web site, and show inventory and several distributors
go here:?
Then enter your OEM part number? in the upper left hand corner in the "cross reference" search box to see the data sheets. Both parts are TO3 / 175W / 800V Vce /15A
While I have not used these particular parts I have had good luck on many occasions using NTE crossed parts. . Both of the NTE parts are also available on Evil-Bay and that retailer named after a river in South America. Sphere is always a good bet and very trustworthy, No affiliation to any of the above...? just satisfied customer

Re: tek part number Prefixes
I have the 1984 materials catalog which has alphabetical and numerical lists.? 119-0000-00 comprises misc electrical components (delay lines, filter chopper, oscillator, power supply, fan, etc.).? Another list I saw included flexible media.? I thought I uploaded those lists to the files area - if not I will in the next day or so.
