I missed this follow-up announcement from eBay on April 19, 2018 which says buyers will still be able to use PayPal to pay for goods until July 2023. After I read this my conclusion was that this

There can be a myriad other reasons for an updated model including: cost savings, customer requests, component EOL. It doesn't always have to be monotonic progress towards ever improving specs. I

Dennis, I always "assumed" that was the case, as I am sure that others did as well. Being a contractual/partnership relationship, that makes the final results less "bizzare". Easier to get rid of a

Sadly, for those of us in rural areas, E-Bay was one of very few opportunities that we had to get our hands on a wider selection of this gear. Not living in or near a large metro area, there are not

Hi Michael, Like you, I also thought PayPal was originally "part of eBay". But in fact PayPal and eBay had a partnership agreement. Dennis Tillman W7pF

Yes, but the reason I’m asking in the first place is that The 501/A is, on paper, more precise and has 4.5 digits as opposed to the 3.5 digits on the 502/A. So is there a not so obvious reason to

Hi, I am hunting for a Tektronix original Service Manual for a DC 503A Universal Counter that I have purchased. I have a pdf of this Manual, but I really want an original hard-copy. I have a hard-copy

The first decent-looking one you see on eBay/other offer? Colin.

Ok so, of the 4 most easily available: 501, 501A, 502, 502A, which one would you recommend?

Sorry about how many replies I'm making. I also noticed the PCB U4494 sits on is quite severly bent, as seen in this album: https://imgur.com/a/fsQ1DrN I don't see anything shorted to the board

Yep. On both my analog/tube DMM and my digital one I have to select what I’m measuring. The only difference is that the digital one detects the measured range automatically, whereas the tube one

For a Tek TM500 DMM recommendation, I have to go with the *DM504A.* it's 4 1/2 digit, auto-ranging, True RMS and has split connections for current, thus avoiding the mis-selection trap of earlier

Is this such a big problem? Almost any multimeter, whether digital or analogue, will surely have the same problems. Just be careful. As I have heard before "A,B,C" - "Always Be Checking". Colin.

Yes, I know they’re not auto-ranging. But, on the other hand, they’re also easier to find. I’m usually very careful with these things, but you’re right, a mistake is never to be ruled

Hi, do not pick the DM501 or the DM502. If you are measuring voltage and without thinking, like I often do, would turn the switch into the current range your object will be shorted by the multimeter

Ok, I did the swap myself and saw no change in the trace or readout behavior. I now have the power supply pulled out to get to U4494. Unfortunately it seems to be thoroughly stuck in the socket, and I

I have just done the swap of J2203 and J2208 on my (working) 7934 and both the signal trace and the readout still work after the swap and no need to adjust any brightness settings. The Z axis input

Dave, I disagree that this is a recession. If you look at all of the numbers this is a depression that makes the 1929-1933 depression look like a sunny spring day on the beach. GOD Bless and

Decisions by boards of directors are rarely logical. They walk a tightrope between pleasing shareholders so that they won’t sell too much of the company stock by doing “busywork” (buying other
