Re: plastic binders for Tek instruction manuals

The binding machines that I have used are big and heavy. For me it wouldn't be practical to own one. I think the copy shop (Kinko's or other) is the best approach to fixing your binding. Don't know about the colors they stock.

Another approach, if you are OK with deviating from the stock look is to buy one of the special ring binders that have multiple oblong rings that exactly fit the hole pattern used for plastic spines.

Cheers,
Tom

Well, I replaced some broken binding posts on a DM502 yesterday. I took the entire front panel apart so I could glue the plastic bedding part together, since it was cracked (you know, "as long as you're in there"). I re-assembled everything, including new binding posts, and was about to re-solder the binding post connections and probe power connector when I noticed I had the extraction tab in wrong.

A couple of hours later, after my disgust had evaporated, I disassembled everything again, reset the extractor assembly, and re-assembled the front panel.

Start shooting the spray on the transistors while watching the trace.
Look a the transistors and don't see a shield of frost building up like
normal, even though I've sprayed them for 3 - 5 seconds. Trace still
bouncing.

Turns out, DeOxit is not a suitable sub for freeze spray...

Evil Bay has lots of em ...but most office supply places carry them....the larger ones (1" to 2" or 3cm to 6cm)  are a little harder to find ...call ahead

If you know the secret ( contact me off list) they are not that hard to replace without the machine..Personally though the ones for my own use  here in the shop that get that way ...I three hole punch and put in a 3 ring binder.. Easier to take a page out when I am working in the shop

Re: plastic binders for Tek instruction manuals

Yes, I just copied an old Heathkit HW-20 manual by removing the comb and copying the manual and the fold-outs page-by-page. Re-assembling the manual took a long time because the pages were somewhat brittle and i didn't want to rip the comb holes open. It helps tremendously to line up the comb holes as perfectly as possible with some sort of took and then clamp the pages together with spring paper clamps. I probably wouldn't have had the patience to do that twenty years ago.

Any idea what the perf/assembly machines go for on the used market?

I bought one of the mechanical perf/bind machines for short money
"over there". Shipping cost as much as the machine !! But it works
very well, up to a 2" spine.

Just look for GBC Binders.

Re: plastic binders for Tek instruction manuals

I did a search on the web for "white plastic binder spines" and got quite a few hits, too numerous to list. I often have one of the local Kinkos bind manuals for me using black spines; never asked if they have white. Probably any decent office supply store can get them. My quick perusal on the web showed spines up to 2"/425 pages.

I have the same problem with a few of my Tek manuals. For some reason, I never thought to look for replacements.

Cheers,
Dave

I have shipped over 60 ….400 series scopes all around the country. IMO the best packaging is bubble wrap. Its expensive but does the job really well.

In my career in computer peripheral sales I watched many a customer do what their packaging engineers  called the “shake and bake”  ( temperature and shock and vibration testing) on products that they were about to purchase ( thousands of them) and ship globally. As to packaging, they said the  best was “foam in place” where the unit sealed in plastic  is immersed in a liquid that turns into form fitting hardened foam.  The worst protection the packaging engineers said was  “peanuts” because they tended to shift in the box resulting in too much peanuts in one place and none in another.

As to bubble wrap, they said it was great stuff but far too expensive to use in high volume shipments. For my purposes, a good sturdy box and a scope wrapped with several layers of bubble wrap always did the job spot on


 

Does anyone know the maximum temperature for bubble wrap?
My reason for asking is that this stuff would seem to be ideal for
attic insulation but never seems to be used that way.... fire hazard?? 

This plus that nice 7K packing box I have stored in the attic.

I designed and built the Pyramid Generator (PG) to be a durable,
portable, well constructed device that would pass the test of time. I
personally detest cheap made items in flimsy plastic boxes that seem to
fall apart if you drop them or happen to set a hot soldering iron on
them. So, I opted for a more expensive die cast aluminum box with
bright blue epoxy paint front silk screen legends that have proved to be
very durable. And, I must applaud forum member Fred (PA4TIM) for his
acute observation that I used a 75 Ohm chassis mounted BNC connector and
labeled it 50 Ohms. The reason is that a 50 Ohm cable terminated in a
50 Ohm connector will fit a 75 Ohm chassis mount connector but not
visa-verse. If you are at an electronic swap meet and have the wrong
cable, are just plain out of luck if you are wanting to test a possible
purchase. The second reason is that the small impedance mismatch at the
low frequencies employed in the PR caused no appreciable
discontinuities. But, I must disagree with Fred when he says that it is
not imperative that the pyramid steps be time correlated to the
display. The PG uses a crystal controlled oscillator and is designed to
display any non-linearities that might be apparent in a trace, Merely
having the beginning and end of a trace fall on the correct vertical
graticule lines says little about the trace linearity over the full 10
DIV display.

Re: DC Loads for Testing 2465B and 7000 Series SMPS

 

Hi,

I recently used Alberts load value to build a load for 3 7704a power supplies that were not working. I added a 3k load for the hv drive lines. I found that one of the power supplies would not start reliably with that load but started easily in it's 7704A.

I am building a prototype 7k extender with a switchable 47watt load. My plan is that it can be used in a mainframe with not plug ins or just the Aquistion (bottom half) of a 7704A. I am hoping that it will work with the non plug in loads to insure start up.

I was planning to try and use a 7603 rectifier to build a test bed for the lv regulator of the 7704a as it has input voltages for the regulator that do not cycle off.

When troubleshooting a switching power supply, it is helpful to use any tricks you can find.

On 7704a power supplies i found it helpful to drive the power supply with a variac. At about 70vac in the supply starts ticking and you can use a scope to see how the secondaries are doing. You look for voltage pulses that proportionally higher or lower than the others. For example pulses on the -50V of -40v with 5v pulses on the +50v line suggest a problem on the +50v circuit.

Dave on some others have a far better understanding of the controller ic in these supplies than I do.
