I remember seeing in the distant past, a catalog picture of a pot/contact cleaner which threaded onto the pot threaded bushing. I guess you would then put in the cleaner/lube, and push a plunger to

Hi ..., I just sent you the TDS600B software. This may work for you. I am not aware of the availability of the TDS600C software. Raymond

I do the same thing for repairing old electronics in general. If it is a sealed pot, unseal it. I just carefully drill a hole like you do Richard.

Hi John, There's nothing wrong with your 7B71. If anything, I am surprised at the speed of unblanking that I see, especially at 100 ns/div. Unblanking is when the beam, which has been suppressed

Hi folks, I have a Tektronix TDS654C that is in need of calibration, as I had to replace a couple of attenuators on the unit. I believe the previous owner must have severely overloaded a couple of

I've got a 7B71 that has problems when in the .05us, and .02us positions. The trace starts at a level corresponding to the trigger level as the trigger level knob is turned. Triggering is in normal

?would be interesting to submerge a "sealed" pot in a liquid and see if the pot eventually fills up, just as an experiment to see just how well these sealed pots are sealed. Some time ago I had to

My foolproof method is to drill a small hole on the top side at the rear. Pump in De-Oxit Fader Lube and seal the hole with some black tape. 73, Dick, W1KSZ [email protected]> wrote:

I have too. Though I have the capability and capacity to do so, I’m rather uncomfortable about making it publicly available without assurance that all the material is legally

I have a spare 500GB disk I could add to my server for that data. The next trick is modifying my website to serve it back to the masses. The rsync from the main server should be easy enough to

I backed it up so it won't go away forever. What I don't have is a place to dump it online with enough storage for even a quarter of it. Downloaded: 37670 files, 136G in 14h 2m 14s (2.76

Try it sometime, I have literally done hundreds this way. Some last week..

An easier way with the modpot is to apply a drop on the red "square" on one side. It flows directly into the the track, sort of... Sometimes two applications are required.

Unless you squirt the contact cleaner in under pressure, I doubt that much of it will find its way to the resistive element. What would be better is to slightly loosen the other 3 screws and again

I saw the explanation for the rubber pad, I think on the VintageTek site, from an engineer on the 2465 project. The reason the pad was included was, there were incidents of the input attenuator

Hi Reed, ?? thanks for your answer. Yes, that is

The pad wasn't available until after the 2465 had run its course, having been introduced with the B models... after serial number B050740, I believe. It was available as a modification kit for all
