A Thermionic Tube, also called an electron valve or electron tube, is an important device in electronic circuits, that combine rectification and signal amplification/modulation functionality. This is commonly used in early electronics before semiconductors, still relevant for niche applications, vintage electronics restoration, and education.

A. Diode on Base: The tube warms the cathode so electrons can flow one way and rectify the AC into DC with 2x anodes for "full wave" rectification. 4mm IEC terminals provided.

B. Triode on Base: A tube with a cathode heater and three electrodes can amplify power with just a small charge. The tube also has 4mm spin free IEC terminals for easy connections.

Dimensions:
115mm (L) x 82mm (W) x 70mm (H)

Wobbly but Usable
Color: Grey, Size: Standard - 4 Panel
A bit wobbly, but good enough for the price when you need a solid background for remote work calls.

Nice and easy to assemble
Color: Black, Size: Standard - 4 Panel
I absolutely love this 4-panel room divider! It was super easy to assemble — I had it set up in just a few minutes. The material isn’t too see-through, which gives just the right amount of privacy while still letting some light through. It does exactly what I needed it to do and looks so clean and sleek in my space. Perfect balance of style and function — highly recommend!

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.
