These are excellent 100MHz analog scopes with a lot of VERY useful digital features and automated measuring capabilities (voltage, frequency, time, etc), plus manual cursors as well. They even have an

DS901-903 (on page 206 of my SM) LAMP INCAND, 14V 80mA, PN 73E, WEDGE BASE, MANUF: GE (08806).

Your (other) MAIN goal...in this case probably try not getting killed in the process, although not sure if the electrostatic HV of most smaller CRTs might give you anything beyond a good bite/shake up

In my case both 10.0K 0.01% resistors R2012 and R2013 where damaged, either fully open or way off value. These two resistors in particular seem to be specially sensitive to the stuff that leaks from t

I forgot to update this thread for some time. The answer to my initial question, can you upgrade a common 2465B to CTT/WR? (options 06 and 09). And the answer is YES. I purchased a "full upgrade kit"

After taking off the case, you need to remove the top processor board and carefully unplug some of the flat ribbon cables. Once that board is out of the way there is a shield underneath that also need

Sounds like a switcher power supply startup random problem. Have you ever recapped it? There is also a number of hi-speed rectifier diodes known for issues that are a must-replace before they fail and

Reach UNDER the chip? Did I misunderstand you, what type of IC type are you trying to remove by cutting the leads? I though you where talking about the NVRAM which is a simple 28DIP package. I have so

Xcelite 170M, been using those for many years. They are excellent and the thick rubber handle makes a huge difference as it allows for comfortable high repetition operation without making your fingers

I'd say Tek designed this scope line to have a constant given airflow. Probably running at less than it is now by trying to control the speed of the fan versus internal temperature might result in the

Also it is normal for these scope series to have a somewhat loud fan noise. This does not necessarily mean the fan is bad unless there is some obvious bearing wear in which case you would be hearing a

That is correct, air exits out of the right side vent. I just checked on my 2247A, same series scope.

Are we still talking about the same subject? These NVRam chips have no external pins to the battery plus side. Some people have gone as far as digging into the epoxy to reach the internal battery + an

Comparing earlier scopes to earlier "vintage" (I don't like to use that world, unless its for clothing) computers is like comparing apples to oranges. Of course an old computer will struggle with any

Are you removing an SMD chip? I think not. You don't think seem very clear on what needs to be done or the appropiate tool. Even just a decent soldapult and soldering pen should be enough if you are s

Why not???? If the scope is up to par and capable there is absolutely nothing wrong. As a matter of fact 8 out of 10 one is probably better off using Tek technology back from the good old days than mo

If it indicates the "OUCH" even without any input there it certainly looks like a problem with the input circuit, or the peak/level detector/comparator that is used to detect an overvoltage condition.

Avoid to buy the NVRAM on ebay, unless you really don't have any other option. No guarantee it will be from a fresh batch, or it might even be a relabeled fake to have a more recent date. Specially if

The GQ-4X4 programmer also works quite well, which is what I used to read my NVRAM, and is also compatible with FRAM memory as well, should you decide to go that route and never have to worry ever aga

And of course replacement of NVRAM prior to recalibration.
