Thanks for the link.

Hello Chuck. First of all, thank you very much for helping me. Thank you also for informing that you were using the cursors in the wrong way. I learned that now. Regarding hybrid ICs, I never

You are looking at the military service manual... it is not the best manual to have. The US military standardized on the Fluke calibrators. You can calibrate your scope with the usual SG503/504,

First thing you need to know is that the cursor measurements are calibrated to be in the center of the noise on the trace, not on the peak of the noise on the trace, so all of the 1.06V, or

Some decades ago (2 or 3) I had a different dual trace scope but am unsure of the model number. It was the size of the 545 with no separate power unit. It had two vertical channels and time base

I've never seen a 555 up close and personal but I have a 556 that I bought for 25 bucks with the full manual at a HAM/Antique radio fest. From what I know it's very similar to the 555 but has it's own

The service manual states that a Fluke 5820A calibrator is required to calibrate the 2467. This instrument is inaccessible here in Brazil. I believe that there must be other instruments capable of

Testing tubes, CRTs, flyback perf.?

from Tim P (UK) re the 555, I've often wondered why the timebases were made plug-in. Was it just for servicing, or was someone at Tek thinking about specialised units (TDR, sampling, etc)? According

Just to chime in. I got a 555 some years back with 2 CA, and a D. I have since added a W, and 1A7. I’ll not mention the initial price, as it was phenomenal. The crt has the purple/blue phosphor for

Yes, the spacings look like you're ready for 40kV!

I'm trying to understand where to start looking for the defect and I really appreciate any help. Checking the service manual, there is a defect flowchart. In the Parametric measuremet trobleshooting

Ernesto expressed interest in a thread about the Type 555, so let's see if it'll fly! :-) For any bench project within the vertical bandwidth of the 555, it's my favorite oscilloscope and has been

That looks rather nicely laid out. Clearly will be a beast when you're done! Look forward to more info. yahoo.com@groups.io> wrote:

Here are some pictures that should give a pretty good idea of what it is - or at least what it looks like. https://groups.io/g/TekScopes/album?id=241896 I'll put up some descriptive info later. Ed

Hello. I hope to be able to resolve this defect with the help of the experienced technicians of this group. I hope that someone will have the patience and willingness to help me. In my ignorance, I
