Cable TV devices
From local factory received some bad, not working, cable TV distribution, amplifying, filtering, coding and mixing modules. It take few photos of this devices. I think, these devices have too much connectors. Especially that smaller one. It is made only from passive components- no transistors or chips…
The bigger one is more complicated- lots of transistors, capacitors, diodes, various inductors and transformers. I picked up these devices as they look interesting and a bit funny. 
Maybe I'll extract some useful components and the boxes are very well made.
