Re: Tek 577 IC socket repair

To replace all the IC sockets you will need 4 8pin dip sockets 5 14pin dip sockets and 2 16pin dip sockets. They are all 2.54mm and 7.62mm, mine fit perfectly

I bought mine from Newark
5 x 19M1525 8pin dip
6 x 95M5018 14pin dip
3 x 19M1527 16pin dip

I also got 95Y3988 which is solder flux that worked well for me.

A good desoldering toll is necessary, I used a Hakko FR300 with good results

Hi Dennis

The list is missing two:

062-0861-01 Storage Cathode-Ray Tubes and Circuits Chuck Devere
062-0955-00 Television Waveform Processing Circuits Gerald E. Eastman

I'm sure that was just an omission from your comprehensive list ;-)

I'm missing one that was on yours though

062-1246-02 Measurement Concepts Transducer Applications Handbook

I have the -00 but not the -02Craig

Re: Complete List of Concept Series and Measurements Concepts Books

Actually, it's missing more than those. Right away I noticed 062-0861-01
(Storage Cathode-Ray Tubes and Circuits) as well as 062-0852-01
(Oscilloscope Cathode-Ray Tubes) was missing.

Thank you Wilson!
For the detailed description of what had to come off and how to accomplish it.
The additional information on how many of which IC sockets need to be replaced, and your source for them completes the 577 IC changing document.
Your 577 information will be in the Tekscopes message archive for many years to come, and will help many 577 owners.
Thanks again!

To remove to mainboard
Remove the pulse, step family, step rate, step offset, zero and aid, display and filter buttons by grabbing the sides and carefully pull while rocking left and right. Some buttons can be removed easier than others and unfortunately some buttons will break unfortunately so be patient and careful. I found what broke on my buttons is the clips which grip the black rods to help hold them in place, though they can still go back in and work they are loose and can come out. On the step offset amplitude knob 2 little grub hex screws need to be removed with a 1.5mm allen wrench which worked for me. The step button in the middle of the step knob is secured by a tiny 0.9mm grub screw by the switch the button connects to, just loosen and the step button should slide out with the rod. To remove the horizontal volts division it is the same as the step knob. When you have both knobs off you will need to remove the bushings which you will see a 1/2 nut for both knobs, use a wrench to loosen. When they are loose you will need to find a way to grab the nut on the rear side of the panel. Remove the 2 little bolts holding the 2 transistors in place, you will first need to loosen with a wrench and then note the little insulator pad as not to forget it when reinstalling the screws as well as the insulator pads the transistors are fastened to on the frame. You will need to note the position of all the trim knobs and cables before reinstalling. Once you have the 4 little screws on the board out and the 2 little bolts on the 2 transistors removed and the bushings and buttons removed, grab the board from the back and pull out carefully, it should slide out. Note there are 2 nuts and lock washers that will fall out when you remove the board so be careful not to loose them. When the board is removed note the plastic rods attached at the end of the switches. I used a precision flat head screw driver and carefully pried the 2 ends pulling out and it should slip off. It might be difficult as my case with some plastic rods but I manged to remove them without breaking them.

I had some help with the Artek manuals, you can purchase manuals from their website if you need a manual, I needed the service manual.

Re: Complete List of Concept Series and Measurements Concepts Books

 

Hi Bob,

I forgot to mention that, unless I am mistaken, the Strain Gauge book was actually split into two books and renamed. The thick book is called "Transducer Measurements" and the thin book is called "Transducer Applications Handbook".

Also, "Oscilloscope Cathode-Ray Tubes" was renamed "Cathode-Ray Tubes".

Hi Bob,
Yikes again. Now I'm really embarrassed.
I did a really sloppy job with this list.
You are absolutely right, there is a Strain Gauge book. I had no idea. It is odd that the cover doesn't match the others but there is no doubt it is part of the series.
I will issue a correct version of the list in a minute.

Re: Complete List of Concept Series and Measurements Concepts Books

Hey, no worries on this end. I apologize about the one I mentioned that
was already covered (my bad for not actually checking the number). And if
what you just said about it being split is true, then that's great. I have
the two! I just don't have the funky orange one. I used to do a LOT of
strange (strain) gaging, but just the physical application on many, many,
many different materials. I don't actually know much about bridge circuits
and measurements. Just how to stick em to stuff reliably in the air, under
water, in vacuum conditions, corrosive environments, etc. Thanks!

Yikes, that's embarrassing! Both of them are on my shelf with all the others. If only I did a simple count of the books on my shelf I would have caught my error. I have no idea how I forgot to put them in the list.

I believe what you called "Oscilloscope Cathode-Ray Tubes" is actually "Cathode Ray Tubes".

7S12 with S-4 and S-53 troubleshooting

Nenad Filipovic
 

Hi Everyone,

This is my first and only piece of sampling equipment, and I can't get it
to work. What I get is a flat trace with just some minor noise on it.

I connected the same signal (10MHz <1Vpp) to both heads inputs just for
test (let's just ignore this blasphemy for now since both inputs are 50Ohm,
and I don't have a S-6). S-53 triggers, I can see the tiny short trigger
pulses from the front connector on another scope. The trace appears only
after S-53 triggers, so I'd say that part works. DC offset also works, and
Volt/div setting increases noise on the trace with higher sensitivity, so I
figure the vertical block of the 7S12 is OK.

So the main suspect is the S-4, but I have no idea how to troubleshoot it.
I can see the tiny sampling pulses being fed to it by 7S12, but nothing
"notable" on the preamp output on pin 4. The manual says not to test the
sampling bridge diodes using an ohmmeter, but a curve tracer. How could an
ohmmeter (actually DMM, <1mA test current) be more destructive to these
diodes than a curve tracer? (provided that the test is carried out using
forward bias only). How to test the snap-diode? Is there any other
extra-sensitive component I should be aware of?

Best Regards and thanks,
Nenad

Re: Time for an inventory or size really does matter

Dave Seiter
 

A buddy of mine has one, and it works really well- I think he's gotten away with lifting 700lbs with it.
I have an air powered hoist rated at 300, which is all I'd put my garage roof through without extra support (I've done 900lbs with a chain hoist and supports).  What I really need is a hoist that folds up, doesn't have long extensions, fits through a narrow door way, has large wheels so it works over grass/dirt/transitions, can lift via a table or sling, and can handle anything form a scope to a pallet of scopes...  we can dream...
When I last moved one of my 19" racks (full), I had to lay strips of plywood and masonite across the back yard- that wasn't a fun move!

some way to get alternating display of two different sweep rates on a 7904A?

John Griessen
 

Is some way to get alternating display of two different sweep rates on a 7904A?

I fiddled with a 7904A and 7A19 7A26 7B71 7B92A and seemed to get crossed controls -- left vert with b horiz
and R vert with A horiz. Then found mention of "independent pairs operation". I'm going to be digging for that in the manual.
Meanwhile does anyone have some hints for getting one sweep at 200 us/div and one at 200 ns/div?

7A19 has zero output on some steps

After these needing a treatment with bond paper to polish gold contacts, remove dust?
Any other hints about this plugin?
