Re: Looking for power cords

ROLYNN PRECHTL K7DFW
 

I am looking for three power cords to mate with the recessed male plug
on the back of my scopes.
=======================

These are readily available (Wal-Mart for example) in 3, 6 and 9 foot
lengths. As a former Tek employee these are close enough to the original for
me and work for the 184 and 191 generators as well as 500 series scopes.
These 14/3 cords will be loafing.

Hi Clint,

Are you referring to the plug-in amplifier (81, 82, etc) or the scope
itself ?

Re: Looking for power cords

John Miles <jmiles@...>
 

Nope, it's a very different connector from what HP used. The older scopes
(and carts) used a conventional male 110V connector in a small circular
recess. Deane's probably right about the cords being unobtainable nowadays.

I would give some thought to replacing the connector on the scope with a
modern IEC-320 plug. Then you can use any standard PC-style power cord with
it, and it won't look as ugly as the extension-cord hack.

It's been too many years since I've used/seen a scope with that power

If so, it
was/is also used in the sewing machine industry and they are
still available
through that avenue.

Deane Kidd doesn't have any left, and says there are no current

LeCroy LS-140 100MHz Digital

Sam Reaves
 

Hello,

I know this is a group for Tek scopes but I felt that someone out
there may be able to help me. I have a LeCroy LS-140 Scopestation 100
MHz DSO. It is really a nice scope. I am looking to find someone who
has the operating system disk that allows the re-loading of the
operating system. This scope has a 386 PC built in with a special card
that has battery backed SRAM on it. I am having a problem trying to
get some of the save/recall data to floppy functions to work. I have
verified that the basic PC stuff works. I think that the operating
system needs to be reloaded since most functions work okay.

Thanks for any any and all help.

Hi,
Can anyone help with the fault on this one? I have readout but no
trace on screen, this is the same on the beam find switch so it
appears that the trace is not there, not just off screen.
Thanks,

Looking for Stuff

kbratz@...
 

I am looking for the following:

1. Plug-in extenders or ribbon connectors for the 561/564 series and
the 535/545 series. If you know a source of ribbon, please let me know
as I may have to make these myself from scrap connectors. In that case,
I am looking for female connectors for both sets. Junk plug-ins are also
options.

2. 184 Time Mark Generator in working condition

3. 067-0521-00 / 1M1 Plug-in for calibrating 535/545 series

Any help that can be offered will be appreciated. If you have any of
the above, let me know the cost.

Thanks,

Ken / WA5JUM

fast storage vs. slow storage?

Robert Morein <morepub@...>
 

The Tek 434 has much slower writing speed than the "fast" scopes.
I notice there was an almost free option to supply a faster writing CRT.
From this, I'm guessing there is some advantage to a CRT with slow writing speed.
Durability, perhaps?
Resistance to burn?
Does anyone have any figures for number of storage hours for the various tubes?

Hi all,

A friend of mine is restoring a 575 curve tracer mod 122C. It's a bit
different from the non-mod 122C manual we have. Is anyone able to help me
with a copy of the schematics (or the whole manual)? Usual costs reimbursed
etc..

Thanks,

7B53A Delayed Sweep

Robert Fincher <robfincher2001@...>
 

Hello everyone,
My 7B53A does not work correctly in delayed sweep
mode, and I've tracked the problem down to a faulty
Miller integrator chip, ckt no U650, Tek part no
155-0042-03. Substituting a similar chip from a fully
functional 7B53A restored mine to normal operation.
So does anyone have one of these IC's that they could
let me have?
Any help would be much appreciated.

7104 CRT required

Hello all,
Does anyone know where I could purchase a replacement TEK 7104 CRT

P31,T7100-31-2.

Thanks in advance.

HV multiplier for Lecroy

Robert Morein <morepub@...>
 

With apologies for my query, because this is related to a Lecroy scope, I think I've found a replacement HV multiplier: an ECG-501B.

Unfortunately, this part does not appear on vendor webpages, either as an ECG or an NTE (who bought ECG last year.)

This is an ordinary five diode multiplier, with a simple tap off the first stage for focus.

The form factor makes it feasible to fit under the HV shield in the Lecroy.

Where could I get this thing?


Re: 2246 With BROKEN COVER HELP

Mark Anton
 

Hi
Before you apply the glue, first melt some wires into the crack, that will help to give the plastic some stabililty. do this from the back side where it wont show. let it cool down and then apply the glue.
Use an old soldering iron, or at least a tip you dont care about, as it is sort of hard to get the melted plastic off the tip.
I have done this for a long time repairing broken tv cabinets etc.

Mark

Household Goop. About $4.70 a tube and worth it's weight in gold. Has a
silicone base but is not anything like RTV.

http://tinyurl.com/g1j9

http://tinyurl.com/g1km

Between that, Super Glue (cyanoacrylate adhesive), epoxy or JB Weld and RTV
you can repair anything.

Out of that list Household Goop is the only thing that will be permanent on
that type of plastic. I've used it to do seemingly impossible things and it
holds with tenacity.

Other choices for some plastics could be Toluene (toluol) or a similar
solvent.

3RP1, etc, in small Tek scopes

 

as I recall, the tube in the 3" models is a derivative 3WP1/2 tube,
which is longer than the 3RP1A, and has MUCH higher deflection plate
sensitivity.

this tube sometimes appeared with the 3WP designation, and sometimes
with a Tek number, but I think the 3WP1 (sometines a P2 for slower
traces) works in all. some tubes seem to have come from dumont or
general atronics, later tubes were all made in house.

don't have any of the correct tube right now, but our Tek CRTs and
cross-ref data live here:
http://www.sphere.bc.ca/test/tek-crts.html

and our EIA type standard tubes live here:
http://www.sphere.bc.ca/test/crts.html

I have also scanned and posted a large amount of basic CRT data here:
http://www.sphere.bc.ca/test/crt-data.html

all the best,
walter
