Dennis,
    If you need a hand with this let me know I am more then willing to help out. For AV currently a really good one is Sophos home. https://home.sophos.com/en-us.aspx I am not affiliated with them in any way but as an IT security guy it is what I use at home. The home account is free and they give you 3 computers. the paid version is up to 10. also look at https://www.malwarebytes.com/ also free for home use. They will usually find things that AV will not find. For PC performance reasons do not run more then one AV at a time. Windows defender sucks and should not be considered effective. and I usually recommend people stay away form Norton and McAfee. not because they are bad but just because of market share. they are the most commonly attacked.

Re: I've been hacked

Hello all,
I receive emails supposedly from Walmart, Walgreans, Associated, Credit One, and others stating that I have won this or that just click on this link to get your prize. The link of course will be a Trojan Horse. Or ones from Charter, your electric company, your bank stating that suspicious activity has been noted and that your account is suspended until you click on this link and login. Of course the link is to steal your login information giving them access to your account or accounts. They will also state that they are from Ebay or Paypal. You can forward the emails to the proper authorities but there are so many of them and the authorities can only do anything if they are based in the US.
GOD Bless and Thanks,
rich!

Re: Viewing hoods for 7000 series

Dimensions of the bezel are 140.5mm x 128.5mm. I'm calling the radius on the corner about .75mm.

The 7104 and 7904 have the same CRT Bezel as the 7633. I have a 7633, so I can use it as a pattern and and I will design one. I'll post pictures of the finished product once completed. I'll share the STL and other files on THINGIVERSE.

FS: UHF and N connector dust covers

Brad Thompson
 

Hello--

I'm offering FS one lot of 75 NOS 5/8-inch diameter push-on flexible plastic dust covers
that fit female UHF (SO-239) and female N connectors. The covers are
marked "A.P.C. A-5/8 Erie, PA" and measure 7/8 inch high.

Dust aside, these caps will prevent coaxial  mites from infiltrating your
equipment's connectors<g>.

I'm asking $8.50 (which includes USPS postage) for the lot of 75 caps--
if there's no interest, I'll entertain
offers for smaller quantities.

Questions welcomed, PayPal honored.

Thanks, and 73--

Re: 465 stopped working

Mlynch001
 

Newton,

I assume you may have replaced the fuse and it blew again? I have had these fuses blow from old age. My 465 blew one just a while back during calibration procedures. I replaced it and it has been fine ever since. Sometimes fuses just give up from age.

Dear Dennis pity, suggestion, get copies og the emails including the headers and forward to security department of your email server or host.

Outlook is not a secure email client

Hey Dennis,

How can we be sure this message is from you and not from some hyper
intelligent AI bent on hijacking the TekScopes list (or worse yet, your
identity!) for its own nefarious purposes?

Just joking around :-) Hope you get things sorted out and that the hackers
didn't get to anything critical for you.

tek 222 operator's manual

michel soldevila
 

Hi,
Just registered in this group, I own 2 type 454 venerable scopes (only one working unfortunately) and a 222 digital storage scope.
I'm looking for the 222 operator's manual. Would any of you have it?

465 stopped working

Newton
 

Hi,

I recently acquired a 465 scope which worked beautifully for my amp building projects. I stored it on it's end (if that has any significance) for a few days whilst I built a new shelf for it. I placed it on the shelf turned on, I'm sure I heard a slight noise and the beam disappeared. Investigating I found fuse 1437 (2A) had blown.
What are the first things to check and how?

I am not used to working on oscilloscopes but have the schematic which I can read so any pointers to get this lovely machine back to life would be appreciated.

Exactly. I use the CURA slicer and it offers this option. If you have a 3D printer, even a smaller one, there are ways to overcome the "too small" Print bed. It all depends on how cheap and how redily you can find one on E-Pay. Since I can print these quickly and for pennies, it does not make sense for me to spend what most sellers are asking for these original TEKTRONIX Parts, when and if they come up for sale.

In my case, I've got the 3D printers, so why not use them? I certainly understand that everyone may not be in that position.

Re: Model for digital inputs on more or less recent scopes

Sebastian Garcia
 

Jean-Paul,

Thanks but, may you be confused? I'm asking about the digital channels
D15..D0.

After some time of searching found it in an appendix of the user manual;
seems to be 100 kOhm in parallel with 3pF for the P6616 probe.

Sebastian.

Re: 466 Repair advice

 

Hi Earl,
The 466 is a very nice analog storage oscilloscope. Unfortunately, I don't have the time at the moment to assist. There's one advice though:
Make sure the brightness of the screen is not too high at any time. Storage CRT's produce less light than non-storage ones and can be burnt much more easily.

Re: Ringing on 2235 100 volt supply

 

Hi John,
Happy that your 2235 is fine again. PSU problems can be nasty with these series but mostly it's flaky contacts, including adjustment pots, as in your case. Good that you found the flaky plate connection, since damage will be done if amp outputs touch e.g. a grounded point.
Thanks for letting us know what was wrong and how things went.

Raymond
