Hello everyone! I hope that everyone is being safe with this virus going around. Now to the topic on hand, I have a Tektronix 515A that I have the bug to attempt to fix, and that is I believe that

Hi Dennis, thank you for the tip. I will order some of this magnetic viewing film on ebay. Hi Jean-Paul I am learning each time more about magnetic shielding. Even at Amazon one can by mumetal

Tom, thank you very much for the site information. I appreciate it very much 73 Richard W4MCD

Curious. I think it also depends on what bandwidth you need, and the repetition rate of the signals. For a low bandwidth, once signal, you need either a storage oscilloscope (rare) or a digital

FWIW a few years ago I installed a 2.2 mA Russian TD in the delay pickoff section of my Tek 547 to replace D 405 and it works perfectly. Morris

I have one unit available here in the US. Contact: electronixtoolbox at gmail dot com If you want more details. Craig

I recently pulled the fan motor and driver board out of my 2465 because I couldn't find a replacement collet that holds the fan on the shaft. I replaced it with a 12V low profile computer fan and

I'm looking for some good 500MHz probes I have available some 100MHz probes.

After replacing all filter caps in power supply, supply ripple is below spec on all voltage's, normal 1V @ 50 ohm output Markers are all working. But 25V @ 1K ohm Marker Amplifier is only working up

Hi Jan, thank you. I found some on eBay. They are tiny, you can pull the from the sockets and mail them to people cheaply. I have some coming, save your diodes for emergencies. thank you,

Also, search for Jim Williams and his design books, this is very good reading! Göran

Paul, I've tried that, sorry does not work at all. --Victor

I am confused, even if "Subject says it all". Maybe I'm just suffering from "cabin fever" with all this staying at home business. Are these 3 P3010 (10x 100MHz) probes as in the text, or however many

Fortunately, the 460A was built well after the time of the capacitor plague. I pulled all the caps from the SMPS on two units as well as inspected the SM caps on all the boards. All the PSU caps

Everything David says is correct. That said, I have one on the bench and it's a fine general purpose scope, but I would not seek one out. It's not Tek's finest work, but it is a good platform for

Hello Richard, I have found many good publications listed at http://www.pmillett.com/technical_books_online.htm The site lists scans of old publications in PDF format. However, even if you do not
