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

I have a type 284 that I am working on again to see if I can’t get the td pulse side working again. Where I am at now is the last time I was in the pulser I was able to confirm that D180 is good on a

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've offered these in the past. I made them for my own use, and for forum members. Since then I have become an Amazon seller so I've added the new updated version of the extenders there (see link belo

I have a P6046 that is missing almost all of its accessories. I need the 10x attenuator, part number 010-0361-00 and 2 of either or both the swivel probe tips, part number 206-0162-00 (hex base) and 2

I just resurrected a 2465A CT. I first want to express my appreciation for the threads here that were such a great help, especially Gregor's "noise on readout" adventure, I thought I would summarize m

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

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

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

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

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

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 *, I start this new thread on the new issue seen after fixing the PSU issue from now ended topic: https://groups.io/g/TekScopes/topic/79486087 ;o) Hands back on the 485and starting from some Servic

I have a Lecroy DA1855A differential amplifier with DXC100A probes. I am trying to calibrate the probes. The calibration manual calls for a PG506A "or equivalent" for calibration. They are using both

Got the scope without probes, Is getting a couple of P6137 the right ones to be used as a general purpose probes? What about HF/VHF/UHF 50Ohm signals? Could I tap these with a dummy load or do I need

Hi All, I'm on a Tek buying spree! I need some gear for development projects and I'm tired of waiting for stuff to magically appear for sale. I need a 576 curve tracer. I have a few analog projects an

Down the rabbit hole again... of unobtainium tunnel diodes, that is. I couldn't get my "new" 3T77A to trigger at all. I'm actually not sure if the 3S2/3T77A/561A combo allows internal triggering or no

Hi all, I recently acquired a *very* interesting Type 1S1. It is serial number B 11, and seems like it is very likely to be a prototype. It's in very nice shape physically, but has serious electrical
