Just wondering if anyone knows where I might get one of the Peltola sockets. I would like to replace one in one of the boards in my 7704A. Thanks, Barry - N4BUQ

Success! Thanks to all that provided help. Your comments and link caused me to look carefully at the Tek files and to reread the included instructions. Upon rereading, I realized I had been copying

Thank you David Templeton, Harvey White and Mark Vincent for responding to my 465B troubleshooting request. During my subsequent troubleshooting I found that, with the AC-GND-DC Switch set to DC, the

Hi all. If anyone out there has a TDS680 scope, can you do me a big favor? I just need a photo of the rear right of the top processor board. In the area bordered by the 4 black plastic PCB

Only if you're talking standard "DOS" formatting. Alternative formats are possible, which might give the additional space wanted. I've not explored it extensively, but on the linux boxes I use

Hello Jon, No no, Alfredo and I don't want to introduce extra loss :-). Jaap

On one 465 I worked on, the ceramic resistor network in the HV regulation path developed a cracked lead right at the body. Sometimes it worked, sometimes it didn't. Took me forever to track that

The firmware referenced by Ken on eevblog is what I have also: Archive: tds3000_3.41.zip Length Date Time Name --------- ---------- ----- ---- 4377 05-16-2001 13:31

just use a 50...75 min loss pad, eg from Mini-Circuits Circuits Jon

Hello Alfredo, Yes, there is a 25 ohm resistor inside the connector. After that all is 50 ohm. The nicest thing is to find a N connector, like on the 2712, and connect that with semi-rigid to the

Hi, I need manual for a sparameter test set Thanks Regards! /g/TekScopes/photo/272750/3383849?p=Created%2C%2C%2C20%2C2%2C0%2C0

Bruce, If you want, I can send you my set, using WeTransfer. Disk 3 files take 1.38MB. I used the set several times to prepare floppies Raymond

Mark, Thank you for the pointers. I will investigate them all. I was able to get the HV up to -1600 V for a few minutes, which was just long enough to verify that the replacement CRT was working and

Jeff, I will take a few guesses to your problem. See if the 10,000 ohm resistors in the -2450v circuit are high/open, C4006 being bad, the .0068mfd condensers bad in some way leaky or open, the two

Hi; There is a thread on EEVBlog about issues with the download. Here is the link along with what should be a good 3.41

Jerome, The 10meg resistors I got from Mouser are 1/2W Xicon 273 series. You may want to get extras in this value for other items. The 1% types have a low temperature coefficient which is better in

Thank you Mark, that is information I can use, along with all the other info I have received from the members here. I really do need to replace the electrolytics. They won't last forever. All the

Jerome, I have a 130LC I restored. I used 1% resistors except, for now, the 33,000 ohm 5W 5% (I plan to make it a 1% type soon) replacement of R95. It is a bit larger in power than necessary. A 3W

There were some floppies that did 2.88 MB, but they were very rare. CD's do 470 mb or so, DVD's do 4.7 GB.? If at all possible, use an SD card or microSD card for cheapest storage. Putting a file
