Hello group! For anyone that is interested in these extenders, either fully built or parts, I ran out of everything from the Amazon orders. I'm sorry that I had to give the Amazon orders priority, but

Hi, I'm looking for manual & schematics for this very nice VOM meter. Can somebody help me? Thanks in advance, Sebastian.

Good Day, The TM500/5000 interface connectors are *incompatible* with the 5000-series o'scopes. Just don't. It's not only a matter of mechanical fit - as Tektronix has wisely prevented incorrect

The FB Old Tek Scopes group should nicely compliment this site. FB is what you make of it. I have mine limited to FAMILY only and not all of them. Think I have 22 or so 'friends'. When I get the

Velik Would appreciate the pictures. I was able to remove them easily from the back side but reinstalling them maybe a problem with getting the mounting screws back in with the CRT in

Hi everyone, i have 2. scope 475. I have recaped both and now full working. But the focus on the second one isn't sharp like the first one. I checked high voltage, 2.72kv for the first and 2.6k for

Dan, Is that image in an album?  There's no way to search for individual images on groups.io yet.  Can we get the album name or the image link? Thanks, Mark

It looks like something has caused XY mode to be activated. If you really wanted XY mode it looks like you should depress only the Ch2 button on the vertical mode selector but having both Ch1 and Ch2

Post from Lloyd Ewing in FB copied below as may be of interest to those in Texas: Does anyone out there live in the Austin Texas area? I just found this group, and I would like to know if there are

Wow, thank you for the interest in my problem. Dave Casey, Dave @Artek Manuals, Dave Wise, DaveD ..... so many Daves .... 😀 To answer a few of your questions .... I live in Melbourne, Australia

I have no idea but I suspect they aren't compatible. If it helps, I uploaded a drawing showing the pinouts for the TM500/5000. The file is Tek500_5000_Pinouts.png. There are a couple of signals that

Dan, these look great but will you be making more? I'd be interested in two. If you're so inclined the "complete kit" format would be my first choice, to save me a few bucks and you some flux smoke.

Hi, I have a Tek 475, that I recently repaired ( faulty cap in voltage divider for HV circuit). I tested the scope and checked as per service manual - worked perfectly. Turned off and unplugged

Dan, Do the electronic components on your board make it incompatible to extend the 5000 series mainframe scopes? I see that pads 3 & 4 are ganged together. Does that also make it

Dave,Interesting device. Thanks for sharing it with the group.George

I found a dead transistor in the Z Amp, which prompted me to check all the Z Amp transistors, but the rest are OK. My 453A does this on the fastest sweep setting, but only half a major division, and
