diyguitarist, The two gentlemen, Michael L. and Ed B., are absolutely right. Others will have great advice as the post. I have the 453 and 4/A series I have restored. I did restuff the main filters,

Unfortunately, that's just the user manual (I was the one who added most of the recent info on that page. So, so far, I haven't been able to find any apps at all. I tried running an undelete on the

After long storage times, old gear tends to get flaky due to mechanical and chemical deterioration in the switches, pots, for instance. A lot of problems can be cleared up by working over all of the

Have you checked the LVPS power rails for excess ripple? You can have "good" voltages and still have excess ripple. This will drive the circuitry to do some crazy things. -- Michael Lynch Dardanelle,

I have a Tek 453 that was given to me like 18 years ago. I used it to look at waveforms of guitar pedals I made and that sort of thing. It had sat unused for probably 10 years until I decided to

Hey Jared, The jitter analysis application looks to be linked on the TDS784 TekWiki page: https://w140.com/tekwiki/wiki/TDS784. I haven't tried it yet, I'd be curious to know whether it works for you.

Hi all, I just got the HDD option installed and working in my TDS784C and am now looking for any of the applications that were available. Does anyone have any of the apps that they can send through to

Try the CRT grid bias adjustment. One clue that it's wrong is if a beam doesn't appear when the intensity control is full counterclockwise (or should I say "anticlockwise"?) and the Beam Finder button

The vintageTek museum has been most helpful. They have the pot and some knobs I am needed. Thank you very much for the reference to them.

I need a Vertical Switch circuit board for a 7104 oscilloscope. Please let me know if you have a scrap one laying around that you would like to sell. Gary

Many thanks Bob; I did already discover that my other Storage board had an absent W250 jumper so I took the initiative to disconnect the one on the board I'm actually using. It worked as it should so

Jose, we have several PS501, some with the meters, all works fine. Open to your offer, we seek any TM500 plugins for swap or TEK 7000 plug-ins Unis location in USA Please contact with PM or emails

Hi Jose, Makes perfect sense. I have both models, and use both for different reasons. Having a built-in meter is definitely handy. The 503 has an LED whose brightness tracks output voltage, but unless

Hello Bob Thank you for the reply and certainly you make sense. But the odd reason for wanting the PS-501 is to have a unit that I can move around in a single rack without depending on an outtside

Why do you want a PS-501 as opposed to a PS503 or PS503A? Except for the built-in meter, the PS503 is superior, having dual +/- 20 volt supplies with tracking capability. The PS503A can supply 1A on

Thanks for the quick responses guys~!~ I checked with Artek earlier, he said the highest referenced serial number is B103xxx and mine is a bit higher, maybe not too high but higher. I’m going to

There are two versions of the vertical preamp board. The older one has dual pots for vertical position, the new, single-section pots. I've uploaded this picture:

I ordered mine and it was delivered a couple of days ago. I am very happy with it. As a Tektronix enthusiast, it is a pleasure to just see this lit up in my shop. I consider this an "accessory" to my

Elsewhere I have recently discussed my 468 repair project. I now have an analog scope working pretty much correctly. However the digital store function seemed to have problems of no display. I

Your basic part number for the manual is correct, but you need a later version. The 5A48 did go through several modifications over its lifecycle. And the commonly-found manuals on the internet are
