I bought mine used from a local reconditioner several years ago and it has had several years of light use since then. It has three flaws (other than these, it appears to work just fine and I have

Re: 2465 - impending U800 failure?
I have a working 2232 that I suspect may have originally been a 2224 which is the uncommon 60 MHz version. Besides some cosmetic discrepancies, the fastest analog sweep speeds have an awful lot of

Re: Anybody know the difference between a 475M and 475?
I can only partially answer this question and I even own one. I have never had the need to open it up as it is the only 475 scope I have ever obtained that is fully functional. I suspect it is very

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
You could be right about that. I had gotten it in a lot of scopes I got from a Govliquidation auction and it was the one I figured was going to be parted out. It had a lot missing like knobs, both

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?
