I have added another picture to the album (/g/TekScopes/album?id=266234) showing all six candidates I have tried for replacing missing thumb nuts on 500-series scopes and plug-ins.

right. I was thinking about a 555 timer chip driving a relay. places like surplus sales of nebraska, or perhaps sphere might have the originals. --rick chinn

will the side panels from other tm5xx instruments fit the AA501? --rick

Hi George, Yes, I will admit that is my bench. In terms of the 465 videos. The vertical section will post on Friday. And I hope to be recording the Horizontal and time base this weekend. That should

Zen, Is this your YouTube channel? https://youtu.be/GYkjuE7Pez8 The videos are great! I’ll be watching the 465 video later today. BTW, I’ve been using Svg2Shenzhen in conjunction with Inkscape to

That was a miss label. Q500 and Q510 are the same part number it is 2 discrete transistors. I have it updated. Zen

I use an Extech LCR200 for in-circuit testing. It computes the overall impedance at your specified frequency. Just make sure you COMPLETELY discharge the capacitors using a 25K high wattage power

Everything you ever wanted to know about ESR and various designs: http://kripton2035.free.fr/esr-repository.html I built one of those designs and it was very helpful. There's also an ESR adapter for

Hello again, My main thread is " 2712 SA with display (and normalization) issues". Due to the large number of electrolytic caps this SA has, I wonder if anyone can recommend a (not too costly)

Thank you! Ronan

Both my PS 503A modules have clip-in side panels. And as to the side panels being perforated or not, my assumption for which ones are perforated and which are not is it is heat-related, but this is

I have a small collection of TM500 plug-ins, of which these have these latches: PG506 1 latch missing TG501 SG503 Both latches missing FG503 PS503A I agree with Dan on the part-numbers, which are also

You can use Python scripts to generate the Kicad footprints for the PCB edge connectors. I've done it for my TM500/5000 and 7000 series extender projects. https://github.com/anotherlin/tek_tm_ext

The trick to gluing the two halves together, if that is necessary, is avoiding the adhesive binding against the side panel itself. This leaves little surface area to bond between the two halves.

Jeff, PG506 has them on at least some examples. These are used only on plug-ins that include the rear support frame. I will need to look as I think I have a couple of others which have the same side

Which one is Q510? I see 2 Q500s but no Q510. Of course it could just be me. Vince.

I have uploaded the schematic that I have drawn up in Kicad in the files section. Given the new information for Q500 and Q510 I think I will need a different part in CR511. I need to figure out how to

Hmmm... Silly me, at a glance I always thought these were just good old fashioned Dzus fasteners, but that shows how little I know about Tek's passion to custom build everything. :-) Keith
