I picked up a 7844 from this seller last week. He's a nice guy and clearing out a scope rehab hobby, apparently. -- Phil wrote:

I have a 7A26 vertical amp unit that is misbehaving. It is housed in a Tek 7704A. A borrowed (good) 7A26 operates correctly. The symptoms are as follows: (1) The amplitude of a given signal does not

Hi Menahem: I should place the illinois capacitor link for comparison to the Nichicon . You'll see for the 50V, 2200uF cap I am using the KXM series (which I use mainly now) has much better ripple

Thanks for the comment Steve ! I look forward to that document posting. Good point on the common mode resolution limitation. A question in regard to the CMRR, is the poor response a function of the

Thanks Dennis, I just downloaded it. I'll look at it. Thanks for the comment.

I am looking for one B1107, 'Power On' indicator bulb, for the Tektronix 453 that I am trying to fix. The Tek part number is 150-0045-00. Does anyone have one that they would like to sell me or can

Has someone compiled a list of the capacitors to replace in a Tek 49x series power supply? I seem to remember seeing such a parts list in the past, but do not readily see how to search the archives

Im using a 50ohm cable a 50ohm through termination and a pg506 fast rise pulse.

What is the source of the signal being displayed ? What kind of probe is being used ?Is it compensated ??Is the probe ground lead connected ? Do yourself a favor & lose the probe.Connect to a decent

Hi Ron, I wonder if we may know each other. I knew a Ron who would be about your age who ran an engineering organization in Cedar Rapids. At the time, I was a brash young engineering group manager in

Sorry Raymond, again I missed you message of a few minutes ago! BTW I sold my one and only 465 some time ago, so I can't help with doing measurements. Albert

They share the same output amplifier.

The vertical output Amp and some other parts, like parts of the channel switch, are common. Raymond

In the end, it is the moderator's responsibility to determine how he or she wished to have the list moderated. I this case, Dennis has laid out how he wishes the list to be moderated. DaveD

You have the proper fast rise generator to perform an adjustment. The risk in my opinion is that you destroy a stuck trimcap or trimpot. You might first verify DC levels in the output amplifier stages

I would think that it's the moderator's responsibility and no one else (elders or otherwise) to filter the various threads. There are certain topics that are completely off topic like politics and

Before you start turning screws: 1. It is not uncommon for the variable caps to become open. I've had that happen to some in the vertical (output) amplifier. I've seen both the rotor not moving *and*

The BW limit switch is off. Turning it on increases the rise time and smoothed the trace like I would expect. verify the setup. Yes but i checked the setup with my 468 (100 mhz) and the rise time was
