You should get the Tek Concepts Book on TDR.Lots of good info there. HankC, Boston, WA1HOS

mentioned. John - Groups.IO doesn't have any sane searching of photo albums, so best to link the album in your messages.

I have a couple TDS754s. An 'A' and a 'D' - while I agree that the 'A' is a little slow to respond at times when doing more processor heavy work, the 'D' is very snappy and responsive.? I find little

That's a LOT of progress Russ! With some more experience you might have thought already of a shorted C1549 after posts by Harvey and Fabio IIRC. One was that as good as zero output is a significant

My TDS784D is only turned on when I need the bandwidth or one of its features, I'll usually reach for the 2467 or the HP54622D - in that order of preference. If Rigol is under consideration, you may

Hi Russ, you mean board A9? I can send you 2 jpg's at 1200 dpi of about 6.5 MB each. Enlargeable until you have the screen almost filled with one component number. When you reply via Private I have

One step closer! C1549 looked like it might have been replaced with a mylar cap. As soon as I unsoldered one side and turned on the scope, the fan came on! So i replaced it with a 47mf 25 v

Hi John, Lack of shielding, maybe (RFI from HV circuit)? I think the '575 doesn't have a shield lid in the HV area, but you can try again with the bottom lid in its place. Regards, Sebastian. PS:

How about some pictures

I have a TDS544 at home, which is somewhat similar to the newer TDS784D, and I really dislike the display, menu structure, and general lack of responsiveness. To me this is the point where Tek went

My 575 mod 122C arrived at the weekend. It did basically work when brought up gently on a variac. I've been through most of the valves and replaced a few which were well down on emmision, including

I'm trying to break the habit of buying old scopes. I'm looking for suggestions 100 megahertz or better, 4 channels, supports a mode where multiple pulses are shown over and over again and shows

It's one of those things you may only use once every two years but damn does it make it easy. I have a 1503 as well as a 1502 and I had to find where in my attic the Romex was tapped into. I was able

I picked up a working 1502 a few years ago on that auction site. The batteries were shot, but I found a paper on using a resistor and a big cap to fool it into thinking it had batteries. I think I

You might, for the sake of general learning, get some breadboard kits, general purpose transistors, and start breadboarding some transistor amplifiers and switches. It would give you a feel for the

Does anyone have a clearer copy of the access board layout? Maybe an actual photo of that page? The only ones that I have downloaded so far are all but impossible to read. Thanks! Russ

Excellent - congrats on the fix.

Which "above written description" are you talking about?? Unless you quote from the email you are replying to, we have no idea what you are talking about.? Notice how I quoted your email reply??

I really like 1502 (not a, b, 1503 etc), and have some I ought to sell. There are two principal weaknesses other than the usual PSU caps: * the tunnel diode is relatively fragile, and can be destroyed
