(fixed) Tek P6201 active probe

[richnormand]

As seen in the photos one of the coupling pin is broken.
The probe itself works well but it is inconvenient when switching attenuator to remove the coupling pin.

Does someone know of the availability of these before I bite the bullet and attempt to repair/machine it?

Cheers and thanks.

I'm going to guess that the only availability of this is other used attenuators, and maybe the spare parts dealers like Qservice (Greece) or Sphere (Canada). It might help to find the part number in the manual and search for that on these stores or eBay.

Can you remove it or is it molded into the plastic? Maybe you could use a precision mini lathe to drill the location of the original pin and press in a new one?

Part number is 206-0200-00 for tip.

Thanks Jeff, James and alm.

I'll look up Sphere. I finally found the manual on-line for the probe.
The plan B is using a cut to length needle and spot weld it to the screw base.
With the proper part number from Jeff I located a few sources. Looks like they are pretty expensive.
Cheers.

Edit: just prepping up the surface and the base is brass it looks like. Spot welding wont work.
I'll use a fine drill bit and a needle to solder it in place in the hole....

While locating a source for these pins I got a temp fix that might be adequate for a while.

As seen in the photos of the original posting the outside pin is 0.1570" long and 0.0300" in diameter.
I usually work in metric but since this is an original Tek part I figured it would match drill sizes better.
To replace the probe pin I used one of the numerous clothing pins I got when I got a new shirt. You can see its remains in one photo.
The shirt needle is 0.0255" in diameter, a good fit for a 0.026" drill using the Dremel in a makeshift drill press.
Located the center of the brass pad with the screw thread and used a jeweler's file to make two V grooves at 90° to position the drill in the middle and prevent wandering.
After prepping the surfaces and the pin it was hard soldered in the hole and cut/sharpened to size. It screwed back in its original position without fuss after cleaning the leftover flux.

Probe works perfectly with the witch hat and the IC accessories.
 
Hope this might be useful to someone in a similar situation.

Looks like that ought to do the trick.
