I just checked the invert switch and when I pull it the trace flashes on the screen and then disappears instantly. Sent from my iPhone

After a day of cleaning and lubing switches and contacts on the 576, it's not as bad as I thought. I used a small artists' brush and lightly coated a few circuit board  traces with DeOxit. Using

Ok, will compare it to my 2465a shield for dimensions.

The implosion shield is just another loose plastic piece behind the blue or clear filter. It's part number and physical dimensions may vary a little bit depending on the serial number of your scope,

One more thing - the S-52 output may appear rather strange due to the pattern of its operation. It's not a simple on/off pulse. Only one edge is the fast one of proper level. It occurs about 85 nSec

Get the manuals for it and the 7S12 - it should be clear and quite simple to set it up for stand-alone running. When properly powered up, the S-52 free-runs and provides a pre-trigger output. Ed

I paid $50 for one on e-Bay. Once I added a big Cap to replace the dead battery pack, it worked. Cute toy, did actually use it, twice. 73, Dick, W1KSZ TekScopes@...> wrote: [Non-text

Hello all, What is a Tek 1502 (no suffix) with X-Y output module worth these days? How much should I offer for one in un-diagnosed non-working condition accounting for most common

This 2230 seems to work OK (analog section - don't know about storage). But the readout of volt/div is wrong on some settings; always going to the next higher reading according to the analog

Pulled the blue lens/filter and the knob, CRT shield looks a bit trickier, never pulled one. Anyone got any advice on extracting that from a 2465?

Pulled the blue lens/filter & the knob. Anyone got advice on how to pull the implode shield off a 2465?

Hi All: I picked up a 17 psec S52 from EBAY and I am trying to figure out the way to power it up and give it a trigger. Can anyone point me in the right direction please? Also, got an S4

The trace doesn't appear at all on channel 2. I got it to come up a few times but not lately and I don't remember what i did. And a couple times I had the cover of it and it worked for a good 10

In the end, there can be only one!   Dan

Since Keithly was was rolled up up under Tektronix after the acquisition by Danaher ( in competition with their now "Step brother" Fluke) I wonder if that means they will finally roll the Keithly

Hello-- This slipped past me: http://www.fortive.com/news-events?page=0 ...And Fluke and Tektronix are no longer part of Danaher. 73-- Brad AA1IP

I encourage you not to give up on your 454. It has a fabulously bright and sharp CRT. I have to ask some of the same questions: 1. Does the trace drift off screen when the input coupling is set

Give it bath! I've bee washing scopes (and all electronics)  for years.  The key is allowing time to dry.  We've had over 30 days of 100+ degree temperatures in Texas this summer, ...so 'drying'

Hello-- "Tektronics"?? The odd font of the letter "S"? Is this a knockoff of a Tannenbaum original copy? ...Or am I experiencing post-dinner digestion-induced mental obtuseness and not seeing what's

Hi AncelB, I don't need all those knobs though, I only need one gray one. If you get busy or something let me know. Thanks,
