Wow you fixed an awesome piece of lab equipment by replacing a little reed switch. I remember a company called the Electronic Goldmine having those reed switches for a buck a piece in the 1990s. Awsome work ❤

Nice teardown and explaining, as always. Here's an interesting idea for you - what if we take, say open LTZ1000 reference module (or other zener), place it in the chamber for picture, and apply power and measure zener with 3458A with fast sampling rate. And then take number of pictures with different x-ray voltages and see if that affects or shifts the zener value in any visible way. Could be interesting to know, if zener output might shift from say shipment security checks at airports too, even without applied power to chip...

Nice tutorial on the X-ray tubes and how they work, I had no idea....but now I do! Thanks.

Thank you, Shahriar, for another great video! These little faxitron units are really good for imaging small items. Many of the x-ray units use a basic two element tube, where the focal spot size is directly proportionate to the filament dimensions. These models use a tube with a biased focal spot. By changing the bias voltage on the focus element, you can adjust the focal spot size down to very small diameters (I think these units are set to .02 or .03mm). We call those "microfocus" tubes. The gun board produces the bias voltage for the focus, among other things. In 1999, I went to school for a new cardiac cath lab system for imaging the heart that used a new type of variable focus x-ray tube. It could achieve focal spot sizes not quite as small as this, but at voltages of up to 150kV and current of up to 1000mA. It was quite the system! Anode cooling was a big issue, as you can imagine! It also used an image intensifier (dynamic DR panels weren't available yet) and the image intensifier had a variable zoom that could track with the focal spot. I foget what the marketing name was, but it was very complicated and expensive and we only sold a few of the units. Thanks for sharing and bringing back some memories!!!

AH! You do have some FINE pieces in your collection! The old Triplett 630! :)

I love how simple you make troubleshooting a device like this. It's illustrated to me how important it is to understand, at least to some degree, how the thing you're working on actually works. Certainly possible to repair things without that knowledge, but that combined with a step-by-step approach makes for a very efficient diagnosis that would otherwise take much, much longer.

Another great video. Teardown video for high-voltage devices are worth to watch just like your RF related repair / teardown videos.

X-ray Shahriar-B. Casual genius.

Hats off to your level of intellect and vast knowledge. Every repair you do you is spot on with fault stage and components to be replaced. Thats called a Mervelous Electronics Engineer.

I appreciate the way you break down your troubleshooting approach. That's something I always struggle with.

This brought back some memories of when I was a BMET. I loved that job. Best in the Navy as far as I'm concerned. Thank you!

What a video! There is no screen wide enough to fully display your genius!

wow, the end result!

Very interesting. I worked for Philips Medical System in Hamburg, Germany on X-Ray systems in another life. Back then instead of USB, control functions and UI were over CAN buses. Thanks for the trip down memory lane.

Excellent video.

Wow, amazing equipment you have, and know how to fix it, and presentation is really good!!

Loving the cat flap for Pooch! :)

A very good video.

great video love stuff like that

Awesome...cheers!
