Tube guard shield mesh

[Algar_emi]

Hi, I’m making tube guard like Allnic is using, I found the tubing, small standoff, etc, but I still need to source the shielding mesh as used in this picture.

FWI the preamp I’m making is using microphonic DHT tube, as Allnic does, so vibration isolation and shielding are a good thing to reduce the preamp noise.

I was considering rain gutter mesh protection as a possible solution. Also I’m wondering what is the best metal to use, aluminum for ease of working with is probably the best solution.

Can someone point me in the right direction to what is this mesh, and a source to get some for my tube guard? Any help appreciated.

Thanks
SB

Check aliexpress. I found something somewhat similar (but check the size, etc.).

Hi, thanks for the reply, but I’m not looking for the top plate with holes, but the metal screening inside the clear tube chimney 😉
I had an original Allnic preamp in for a few upgrades, and I saw how the screen is made, just a metal mesh inserted into the tube.

Quite common on air filters of agricultural and industrial vehicles, but also on small diesel engines such as Yanmar and Lombardini.
