^ with him/her. I'd be perfectly happy with as-is stated performance and 3D printing an enclosure.

Will something like the old conductive carbon spray for coating the CRT TV case internal or the CRT tube work ?

If it will work for EMI shielding then it will probably work.  The cases on the Apple 2 computer used something like that on the inside.

I think for EMI it is better to use this one on a plastic enclosure (kontakt chemie EMV 35 or EMI 35): https://uk.farnell.com/kontakt-chemie/emi-35-200ml/coating-conductive-emi-35-200ml/dp/2142398

the Willows:
Very interesting, was on the way to order from the German guy, but this seems to be a much better design.
Please write me up for 2 pcs.

We own (me and Daniel from Xtreemtec) since last december a LeCroy WavePro 7300, but no probes yes. Hard to find item or huge prices.
So this is a good alternative.

Are there any probe kits remaining? I'm interested in one. Thanks.
