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.

Light weight and large privacy screen
Color: Black, Color: Black
The privacy screen is light weight and of great quality. The screen can block sight and also is easy to set up. It screen is sturdy and stable. It is a cheap solution for separating paces in rooms. The privacy screen is of black color and good good in many places. It can be folded when not used and does not take much space for storage.

Great divider!
Color: Black, Color: Black
This was really easy to set up and really works to decide the room. The material is dark enough that you have your privacy. Good for the price

Over all review
Color: Black
It’s not a bad divider, the instructions are okay but once I figured it out on my own it was easy. The quality is fine I like how it’s made of metal. The only downside is fall for me is the height. I’m 5”4” yet it’s suppose to be 6 feet tall but it seems to be a little shorter than that. If it was taller and the instructions a little more clear it would get 5 stars.
