One platinum matched quad (4 tubes) of rare EL84 6BQ5 EI Yugoslavia made back in 80s.
They are hi quality EL84 pentodes, made under Mullard / Philips licence and on original Philips / Mullard tooling. Gray plates, halo ring, copper grid posts, three slots in plate. They can be used in all EL84 / 6BQ5 applications.
The same Philips Heerlen EL84 tooling was used also in Mullard Blackburn tube plant (early version, later versions had one hole instead of three slots), Valvo Hamburg and Siemens. These tubes were made in early 80s after EI Nis tube factory has bought complete Siemens Munich tube plant with all machines, materials, stamped plates, cathodes and winded grids. That's whay they are more expensive than some other EI batches, but they really sound like genuine Siemens - Philips EL84 / 6BQ5!
They are carefully matched by plate current and transconductance on my Metrix and Hickok testers.

Easy assemble and not to big!
Color: Black, Size: 132in-Large Metal Base
I bought this because I fo a lot of zoom/teams meetings and work just mandated no false backgrounds (don’t ask) soooo to hide my real home and allow others to roam free while I work I got this. Easy to assemble although you will need some space. I thought I might be to big at 11’ wide as I have a small desk area but actually it’s perfect and could use a couple more panels. Leaves just enough room so I’m not completely cocooned - I can move my chair and get up walk behind chair and exit space. Great deal and tax deductible!

Fair Quality, Hour and a half build
Color: Black, Size: 132in-Large Metal Base
Key things: It does (more or less, not completely) fold in on itself, it does block nearly all visibility (especially from an angle), it was only about an hour and thirty minutes to put together, and it is light weight.
Do I recommend? Yeah.

Assembly was a bit rough
Color: Black, Size: 132in-Large Metal Base
It is serving the purpose it is bought for. However the assembly was harder than it should have been.
Joining the parts A and B (two iron pipes) was very hard. We can't use any tools to do that and it has to be done manually and every joint was very tight and very hard to to do. I had to struggle to make 24 joints for the length I need. At one point I was going to return it, but I needed it very badly so continued with the assembly.
