Sam, in mine it was the resistor in the HV box. You could have a look inside this box and look if this resistor is getting hot. Its on the right upper side under the metal

My personal criterion is that I should be able to remember the location and condition of each scope I own and how I acquired it. I should be able to list them from memory. When they start blurring

I think the "-57" on yours is the single sweep option, mine doesn't have that, so I'll just have to guess. Are you saying the single sweep works? If so, is that repeatable? Or did it

Don't have a complete inventory - from memory, some in multiple copies,some parts units; 511AD, 512, 513, 514, 519, 525, 526, 528, 529, 531 brown, 531A, 533A, 535brown, 535, 535A, 541A, 543, 545,

I believe mine has the P7.

The toggle switch is "Single Sweep / Normal". Not an extra light, it's a button, label "Reset"

Hi all, I am about to calibrate a 2465B, but I have no tunnel diode pulser. The parameters are gone from memory. Is the calibration the same as the 2430, that you have a program that expects the

Hi, Cliff -- I did this, sawtooth out jack is steady at ~ 19 volts, delayed gate out, zero. I switched to "Single Sweep" (speed at 1 cm/sec) and saw the spot move to the right -- once. After a few

Sorry about the incorrect reply - there are two troubleshooting threads currently open - a 532 with no sweep, and the 515 vertical. I am contributing to both and replied to this one incorrectly)

Thanks Jerry, I can take a photo just for you to see, but on one of them all letters gone... so no point checking your stash for that (supper thanks for the kind offer anyway.. if it was just one, I

OMG, these are pretty much instruments. For my part I am happy with my fewTeks: 547, 564B, 180A, 1A1 (Bad CH1 Nuvistors), 1A7A, CA, 3A6 and 3B7. For thefuture I hope to get a Sampling system (1 or 3

Cool! I hope the rest of the instrument works fine. Pay attention on theHV-Supply, I don’t know if you already hear it, but the transformersimpregnation is infamos for absorbing moisture, so that

So now the question is: Who has more scopes etc? - Craig or the Tek museum? Bob

That's too bad, but not surprising. I wonder if the 7844 runs just enough hotter than the 7904 to cause this problem. I've had two 7844s with bad transformers, and three 7904s with no problem at all

Hi Bob, My left, as observed from the operator's perspective, sitting in front of the screen. I've received some valuable analysis from an off-list e-mail. I've asked permission to quote, then post

I forgot about those - I used them for making front panels. I would put the letters on, then spray with clear lacquer, let it cure and then bake the panels briefly. For buttons, one could spray some

Remember dry-transfer lettering sheets? I don't know if any are still made, but modern and better equivalents probably are - I'll have to check out that website - good info. I still have many of

from Tim P (UK) I think that is a single-shot option - the original532 didn't have one. Some of them may have had P7 phosphors - the 'scopewas popular in the BioMed / Engineering fields, where 5MHz
