I have a very nice 549 that I have owned for nearly 35 years. It worked flawlessly at first, but then began showing the infamous epoxy HV transformer potting issue. Back when it started doing this ('8

A year or so ago I bought a TDS784C that seemed to be in pristine condition except for a missing left rear foot. It powered up and worked perfectly on every signal I tried it on. I found that I rarely

Hi all sampling gurus, I am continuing performance check of my 7S14 (B020274). Any idea how many pieces were manufactured? All the Hg cells were empty (and were leaked also). I replicated with the con

Hello everybody, I am writing about the attempt to transform my TR503 into TR502 to use it with the SA 7L13. I started by replacing the 55 MHz crystal with a 52.5 MHz one (thanks James) and after some

Hi All, My TG501 1ns output died. I suspect it's CR515, the 4V hot carrier diode at the start of the 1ns section. It's just a rare sized barrier Schottky. If I understand the circuit correctly it adds

First time poster here. I’ve been reading many posts and learned a lot from you guys. I got a 465B from eBay and I’m having a problem with getting the trace to focus properly. Even after checking and

Hi, everyone. I've been working on a Tektronix 606A XY Display but the unit resists all my repair attempts. So, I'm reaching out to this group for suggestions and assistance. I've documented my proble

I hope this is an appropriate post. I have a bunch of TEK Equipment that I will never get to, but would like to see get a new home. There is no charge, but they are available only for pick up in West

I recently acquired a P6201 active 1X FET probe which appears to have never been used. The inspection tag was still attached, the accessory pack was still sealed, and there was not a single mark on th

When I bought my 3S2 sampling plug-in, it came with a 012-0124-00 Sampling Head Extender (3 ft). Thought that was a nice bonus. Unfortunately some genius seems to have removed the push-on coax connect
