That's the hybrid containing the six microscopic Schottky diodes for an S-4 sampling head. Is there any source for a replacement, or is there someone who has the tools to replace individual diodes? Go

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

I bought a very inexpensive 7623A on the auction site and it just arrived. The aluminum cover on the back was dented in, and there was some damage to the low voltage regulator board (the fuse was shat

I have used Tektronix scopes since the 60s. They have always been the gold standard, at least as far as I am concerned. Now my old Tek scopes, I have 4, are getting old and keep requiring service. The

In 2017, my 547 with Bill Schell HV transformer (installed around 2000) was working. It has sat unused in a dry basement since then. Today, in March 2021, that transformer exhibits the same thermal ru

Dear Forum, I have an old Tek TLA700 Logic Analyzer complete with software disks: Application V 3.2 - 063-3022-04 ( 2 x CDRom ) Controller BIOS 1.00.14 for TLA704/711 - 063-2895-02 (1.44 Floppy) W98 B

I mailed all of the international orders for Peter Keller's book today with the exception of the five going in one package to the United Kingdom via UPS. Those will be mailed as soon as I get the pape

Is there a resource for the sockets that are soldered into the PCB boards in scopes with plug-in transistors, ICs, diodes, etc.? Dave

Sometime ago I bought a sealed copy of this Tek software: WSTRO & WSTRU WaveStar Software for Oscilloscopes, WSTRM WaveStar Software for Meters. The label on the back says v2.4 Tek part number 020-235

Running an up-hacked TDS3014B, and am seeing small amount of what I'll call "ripple" on the top of the calibrator signal (i.e. the 5V part of the signal - the 0V end is relatively stable by comparison

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

Hello all, I forgot to state that these are 260s. Sorry! GOD Bless and Thanks, rich!

My 2467B has developed several problems with the display; I'm not sure if they're related or not but they started about the same time. The first is if I put a sine wave on the screen and center it, it

With the voluntary help of many of you on this list, I successfully re-caped the LV PS on my 2465B and in the process, fixed the intermittent power-on failure (it was one of: LV PS, on/off switch, or

Hi guys, my first post here. I have been given a Tektronix 2230 scope. The previuos owner could remember het go it from somebody else, and there was something about a fuzzy readout. I always find it a

I wrote a few weeks ago about no Horizontal trace on my TEK465. In the meantime I have replaced bad caps and transistors to the point where I have a sweep signal going to one of the CRT grids. I do no

I have a few surplus 119-0262-00 Crystals. They are adjustable for fine tuning through a screw hole on the top of the package. These 5MHz crystals are used in the 7D11, 7D14, and 7D15 plugins and poss

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 *, 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
