Yeah agreed. I’ve fixed more Tek equipment than most people out there. In the order of hundreds of units.

These are just exceptionally bad.

i thought maybe it was just something regionally here or the way people stored em, but i was in a position to refab many a few years ago and totally agree. tek had 100% repart rate and seemed like anything else (brand wise) was always in better condition internally even when way older.

I'm blanking on the exact models I used; I'm fairly certain they were tds700s or tds71xx, but a lab I ran had about a dozen units and we had nothing "fry" in the 4 years I worked there. What applications would result in these catastrophic failures?

  • Over the years, I've had 5 TDSxxx series scopes, and I still have a few. The common issues are:

    NuColor CRT displays going bad. Bad capacitors. Dallas NVRAM units battery running out of juice

    Fried electronics are pretty rare.

    • We had some "ghosting" on the displays on a few now that you mentioned it, but they were still 100% usable. I guess my expectations were lower since I never had to foot the bill for the lot of em (which at 20k/unit I guess I'd be upset about when one was faulty)
