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.

Pretty Color & Lighting
Color: Pink
I found myself needing a keyboard case for my iPad pro (10.5 inch). I stumbled across this one with great reviews. Once I opened the box it arrived in, it lived up to its reviews. The case feels smooth and appears to have great quality. The keys on the keyboard sound like a typewriter which I love. I was unaware that the keyboard lit up but to my surprise the lighting was extremely bright even in the daylight. The weight of the both the keyboard, iPad, and case all together feels as heavy as a FiveStar notebook. Connecting the keyboard to the iPad was the easiest part because once you pop your iPad in the case and turn on the keyboard and press the connect button you head to the bluetooth settings of your iPad to pair them. Performance wise sometimes the keyboard snoozes after a few minutes of not being used and takes a second to start typing again. Besides that it works great when you’re constantly typing. Overall I love the color of the case and it’s definitely a money spent well.

Good value for the money
Color: Purple
This is a great little case. This is used for my elderly aunt and uncle’s ipad which doesn’t get a lot of use. The case is protective and opens up to hold the ipad at a couple of different levels. The keyboard is not as smooth as the apple keyboard I have for my own ipad but it really works well, holds a charge for a long time and was a great price.

The keyboard fits nicely inside for easy travel. It charges easy and comes with a charger for usb. It connects when on and turns off if not in use to conserve the battery.
