I am a little surprised that the A trigger centering adjustment could not calibrated that offset out but with Q522 bad, the trigger sensitivity could have been screwed up anyway. Do you have any idea

Good job Stan. Thanks for sharing your results as I am sure someone in the future will benefit from your work. Regards, Tom

SOLVED...while pin 3 of U520 had a good copy of the waveform being triggered on, the DC voltage on pin 3 was 1.6v. I found the U520 pin voltages posted by Tom Miller and noted that proper voltage for

I bought a can last year right off the shelf and it can with an extension nozzle, nothing else. What am I missing? Do I want to know? Dennis

Where the heck do you live? Wouldn't it have been easier to just buy it locally?

Don't worry, you'll have plenty of time to read them all in the */next/* forty years. Don Black.

I had a depressing experience last week. I bought my 2nd can of WD40 in forty years. (Yes I don't spray it on everything and that's why the can lasted 40 years.) First can was bought over the counter

Hello, I keep trying to isolate. I finally after lifting connections 8, 9, and 10 from T550, am able to turn up the variac without blowning the 1/4 amp fuse. 95 volt test point reads 135vdc. If I only

Dave, The pins for custom signal connections could be ignored in an extender cable. Those pins are to allow the user to interconnect the rear in/outs between plugins. For ex, you could take the

Great piece of temperature measurement by Patrick. The grp can consider two ways to measure the temp with cover on: 1. Use a good thermister- EPCOS B57862S282A9 Miniature Bead Thermistor. Not so

I have a 8660C which I use frequently. One of the plugins will allow you to go down to 10 kHz, another up to 2.6 GHz and that is very nice. Yes, these are very heavy. I found that mine (and apparently

I have an HP 8660D which I like. It uses plug-ins and will generate signals up to 2.6 GHz with the right plug-ins (and the 11661B optional frequency extension option). I also have a couple of 8660Cs

Hi Gordon, I am in Brazil and would like to BID on the TR-503. Can you ship to me in Brazil? If this is OK, I will put some bids, but ebay say that "Th=e selle cant send oversea". Please,

I have the 8642B and highly recommend it. 100 kHz to 2.1 GHz range. Extremely high quality CW, AM and FM signals. Frequency sweep capability. It is quite heavy, though. The 8648 models are newer,

Oh boy.... well, OUR starting point fix for these scopes is to re-cap all of the LV caps... Take the cans off the board, re-stuff, and replace..... Got to start somewhere ! Our experience with these

I'm with the school of thought regarding not stressing U800 mechanically, so I used this particular heat sink. One thing nice about the 2465A/2467 generation is that they still have

Hello, Finally got back to repairing my 465m scope. Still can't figure why I'm blowing the 1/4 amp fuse. I powered up the scope with a variac and increased the unreg 32 volts to 20 volts before

Two points .... first, you need to get a unit with Option 002* installed. ?This option gives operation from 512 MHz to 1024 MHz. ?Without it, the generator will INDICATE the higher frequencies, but
