Hi David, I mean if they will still be providing good service, as today we provide the venerable old Tektronix!.

My first 422 still works like the first day, and keeps a pristine beam in the new home, sold it a few years ago. Gabriel.

Re: 2465B - Error Codes

Hello Nandgopal
I would also ckeck all the smd caps 10uF and 33uF on the board. Have you tried to calibrate it? Before you go to changing the NV ram TRY and go thru the complete cal procedure. Regards M8JPK

Re: Solder Sucker Recommendation?
A triac can control many watts and does not take up much space. Plus, it is
a 240 volt unit so the current is not that high. Just look at the size of a lamp
dimmer.

They just need a few watts at low voltage for the fan and control circuit, the heater voltage is fed straight through.

I'm intrigued by how small they can now make a 420 watt power supply
now. eBay item 280783317481.

Re: Ebay seller Mountop
Looks like they had two units. One working and parts unit. Did they ship the wrong unit?
================================================== It appears the two listings are for the same unit as the seller ended the first one ("This listing was ended by the seller because there was an error in the listing.") and apparently cobbled the unit to re-list it. The entire listing description of only 14 words is a little too vague for me to have any expectations of receiving a 100% working and calibrated instrument. Especially for $177.14 to my front door. "Unit powers on. Power cable included. Small damage on back side. Testing seems accurate." The word seems doesn't give me any confidence. Two channels connected to the cal output was probably the extent of their "testing". RP

Ebay seller Mountop
Hi,
I received a 2246A that was supposed to be fully functional with power cord and it did not have the power cord. It does not pass self test and does not autocal. The seller asked me if I wanted a refund for the power cord. Does anyone know these guys? Jerry Massengale

Yes, many of us think in terms of how long a AA battery will last.

Re: Lady Luck
Yes, it does have highly active Lithium in it that must be disposed of
properly. I can provide that service at a very affordable cost.
Just let me know. BTW, I would not trust these other unverified denizens to
do the correct thing :).
Anyway, good going. Things in life seldom work that well.

Re: After 30 years, the modern and sophisticated digital oscilloscopes of today, ??
Why wait 30 years? They do not work that way now and even their
resemblance to early DSOs is fading. If I designed a DSO from scratch, it would resemble an old DSO more than a new one by preference.

It's actually contagious too, all your scopes will get it unless you promptly ship it here... for environmentally safe disposal...

Nope, you can change those figures at will... How about peeking inside the case to see what's going on in there....

Wow, the 2467B has 435 hours and 23 start/stops. Is that tamper proof? It doesn't seem probable.

I totally agree. We had already agreed to meet again because he has more test equipment for sale in storage. He said he used to own a fiber optics backbone manufacturing company that he sold. He fishes and hunts now. I have lots ammunition reloading gear (dies, primer, powder, brass, bullets, etc) that he's very interested in, so I will have the chance to show my appreciation.

I should go to Vegas this week.... crazy. I responded to a Craigslist ad, a retired gentleman had some 'electronic test equipment' he was selling. He wasn't sure on the models, but had a couple of oscilloscopes. I met him in the parking lot of Cabella's, and to my surprise he had a Tek 475A and a 2467B. Probes, manuals, the whole enchilada. He sold them to me for $200 (total). I figured this is too good to be true, there must be something wrong with them. I figured the 2467B would cover my cost if I had to part it out. So I got them home just now and the work... I can hardly believe it. It still has the calibration report from 2000 in the pouch. This screen is bright.

Re: Can a 7844 use two 7CT1N plugins at the same time?
Very good question. Unfortunately I don't know the answer. I didn't think to
toggle quoted messageShow quoted text
try that in any of my other 4 slot scopes for some DUMB! reason. Even as I think about the possibility I am not sure if it will or will not work. I have returned the 7CT1N to Jerry with my thanks. As soon as I get another 7CT1N that will be the first thing I try. Dennis
-----Original Message-----
From: David, Sent: Tuesday, May 07, 2013 4:23 PM Will this work in any other 4 slot 7000 series set to ALT/ALT mode? The mainframe would not be able to chop the signals together so I guess it would depend on how the 7CT1N acts to duplicate the signals that two timebases would generate in horizontal ALT mode.
