Re: 2465 - impending U800 failure?
2465b helpful? My a*s! This Russian immigrant is a cheat and charlatan - search back on the forum - and you will see where he has sold perhaps hundreds of 2465-series scopes which were "modified" by

Re: R7103 backplane repair
I have seen two common types of aluminum electrolytic capacitor wear out syndromes which could be considered chronic versus acute. The chronic case involves a high ripple current application where the

Re: R7103 backplane repair

Re: 2445 CPU Address line failed
I think it has been discussed here before but I do not have a link to where. Maybe there two different versions of U800? wrote:

Re: R7103 backplane repair
The first 7834 I bought which has the bad CRT geometry, maybe it was dropped during shipping, does that occasionally and my 7904 does it as well although less often so far. I suspect the power

Re: Tektronix DMM-4020 Opinions?
Hi David: That is good information to know. I have been looking for good overall bench DMM for some time, and stumbled upon this one. When compared to my Fluke 867B this seems like a real bargain! Are

Re: Tektronix DMM-4020 Opinions?
It's not a Keithley, it's a Fluke 8808A. At that price you might as well try it, you would have no trouble reselling it.

Re: 2445 CPU Address line failed
Actually, my neighbor has an aggressive pit bull -- it gets close enough to us that no 'scope is needed, but a laser sight might be useful for when it hops over the fence. My take on this -- most of

Re: scanned: 1958 Tek Personnel
Maybe not. On page 58 of the 1958 photo album, we find the same photo of Ms. Lusk, with the same calendar. Perhaps the photo was taken in 1953? Also, I got one of the possible years wrong; it would be
