No, not at all.

Any socketed semiconductors on that Z-axis board? I guess not. Try tapping the PCB while 'scope is on and see. Components themselves sometimes develop intermittent contacts. Raymond

Cheeter asked: "Does anyone see a reason not to use UHU Endfest?"Yes, I do.? It has a very low temperature range (80 Deg C max).? They also make no mention of electrical conductivity.? While most

I found five new boxed tubes in perfect condition during the after-stuff-day clean up effort. I believe this is used in the hp 410A probe, if you need some. Also found a box of old (but new in the

Good news! The 7854 works perfectly now! But I don't know how I did it! Here's the story. After some (long!) mumbling I tried to disconnect peltola connectors J91 and J78 to exclude some bad effects

Could well be a grounding problem. Are both instruments grounded? Raymond

With a differential probe P5205 connected to the 754D with the negative on the chasis ground and positive measuring the base of the 177 test fixture some strange results occured. I found if I changed

Sorry, that was the wrong link. The right product is UHU Endfest 300. Datasheet here: https://media2.supermagnete.de/docs/uhu_plus_endfest_300_eng.pdf

Does anyone see a reason not to use UHU Endfest? Here's a datasheet in English: https://www.uhu.com/content/dam/boltonadhesives/products/import/57/en/3950/50.pdf It looks like a good contender for an

Ok - some progress. I replaced the battery. No change in startup (front panel controls still hang until I fiddle with the buttons for about 45 seconds). It's now returning to the previous state after

Also, add C11 to the list of suspects. Dave

How long do the Loctite, MG Chemicals, Hardman, and Circuit Works epoxy glues hold after opened? Days, months, or years? Thanks

Ouch, I'll steer clear then! Thanks!

Q143 shorted would explain TP183 at 120v. It certainly won't hurt to check Q173, Q183, Q184, and associated components just to rule them out. If the mis-aligned P132 connected -50v to the -15v rail of

HI all, I think I was chasing (my own) ghosts trying to find the cause of the limit errors 113..... Yep, I did all the preliminary steps in the calibration manual before going to Cal 1 etc. Nope, U300

I added the EDX-1 Electromyograph Storage to the Tekwiki as I noted I can do in the following thread regarding: /g/TekScopes/topic/30811424#155767 Here is the new wiki page:

I have a cable end with a 4, but that's from a 1502. It goes somewhere into the wiring harness, but I'm not quite sure where and what's connected to the other end. Don't have the matching end. I have

I mentioned 7A22, seconding a recommendation of another in the thread. It doesn't make much sense if you already have 7A18's. The difference between the 75 MHz of the 7A18 and the 100 MHz 7A26 in a

Paul, if I recall correctly, ITW Paktron makes 0.152 inch spacing connectors.? Probably Digi-Key and/or Mouser sells them.Jim FordSent from my Verizon, Samsung Galaxy smartphone

Greetings, I dunno how much I would trust a glue to hold down the connector . From looking at the picture I would be inclined to drill a fine hole on either side of the pin or pins and tie it down
